The complexes CuLn (ClO4)2 · xH2O (L = 1,2-diaminocyclohexane ; x = 1, n = 3 ; x = 0, n = 2) have been synthesized from solution. The complexes [CuL3] (ClO4)2 · H2O (1, sky blue) and CuL2 (ClO4)2(2, violet) have been characterized by single crystal structural analyses. In complex 1, copper ion possesses distorted octahedral geometry having N6 chromophore but in complex 2, copper ion possesses distorted (4+2) octahedral geometry having N4O2 chromophore. Complex 1, on heating, transforms to 2 accompanied by a sky blue to violet thermochromism, a unique example of a change followed by deaquation-deamination-anation reaction in the solid state.

Diamineruthenium(II) complexes containing the hemilabile methoxyethyldimethylphosphine ligand, [Cl2Ru(Ln)-(eta 1-Me2PCH2CH2OMe)2] (2Ln) (n = 1-12, Scheme 1), have been synthesized from the starting materials Me2PCH2CH2OMe, [Ru(COD)Cl 2]n, and the respective diamines L1-L 12. The structure of complex 2L5 reveals that two chlorides are in trans position, while in complex 2L11 the two chlorides favor a cis configuration. Most of the complexes are highly catalytic active in the hydrogen transfer reduction of acetophenone. The experimental study indicates that the replacement of phenyl groups for methyl functions in the ether-phosphine ruthenium(II) complexes resulted in a switch of the hydrogenation mechanism from direct hydrogenation to transfer hydrogenation. The reason is attributed to the better donor ability of methyl groups compared to phenyl substitutents. Thus the metal center becomes more electron-rich and inhibits the binding of dihydrogen to the ruthenium(II) complex fragment.

Synthetic routes to aluminium ethyl complexes supported by chiral tetradentate phenoxyamine (salan-type) ligands [Al(OC6H 2(R-O-R4)CH2)2{CH3N(C 6H10)NCH3}-C2H5] (4, 7: R = H; 5, 8: R = Cl; 6, 9: R = CH3) are reported. Enantiomerically pure salan ligands 1-3 with (R,R) configurations at their cyclohexane rings afforded the complexes 4, 5, and 6 as mixtures of two diastereoisomers (a and b). Each diastereoisomer a was, as determined by X-ray analysis, monomeric with a five-coordinated aluminium central core in the solid state, adopting a cis-(O,O) and cis-(Me,Me) ligand geometry. From the results of variabletemperature (VT) 1H NMR in the tern-perature range of 220-335 K, 1H- 1H NOESY at 220K, and diffusion-ordered spectroscopy (DOSY), it is concluded that each diastereoisomer b is also monomeric with a five-coordinated aluminium central core. The geometry is intermediate between square pyramidal with a cis-(O,O), trans-(Me,Me) ligand disposition and trigonal bipyramidal with a rrans-(O,O) and trans(Me,Me) disposition. A slow exchange between these two geometries at 220 K was indicated by 1H-1H NOESY NMR. In the presence of propan-2-ol as an initiator, enantiomerically pure (R,R) complexes 4-6 and their racemic mixtures 7-9 were efficient catalysts in the ring-opening polymerization of lactide (LA). Polylactide materials ranging from isotactically biased (Pm up to 0.66) to medium heterotactic (P r up to 0.73) were obtained from rac-lactide, and syndiotactically biased polylactide (Pr up to 0.70) from wicso-lactide. Kinetic studies revealed that the polymerization of (S,S)-LA in the presence of 4/propan-2-ol had a much higher polymerization rate than (R,R)-LA polymerization (kss/kRR = 10.1).

An efficient one-step synthetic strategy was used to prepare a set of dicarboxamides through palladium-catalysed aminocarbonylation of iodoalkenyl and iodoaryl compounds, with use of various alkyl- and aryldiamines as N-nucleophiles. The isolated yields of the dicarboxamides depended significantly on the iodo substrate and diamine structures, as well as on the reaction conditions, the best one (ca. 70%) being achieved with 1-iodocyclohexene as substrate and 1,4-diaminobutane as nucleophile, at 100C and 30 bar of CO. When iodobenzene was used as model aryl halide, the highest yield of the target dibenzamides (ca. 65%) was obtained with 1,4-diaminobenzene as coupling amine, at 100C and 10 bar of CO. Preliminary studies on their in vitro cytotoxicity against human lung carcinoma A549 cells showed N,N?(butane-1,4-diyl)dibenzamide and androst-16-ene-based dicarboxamides to be the most efficient cytotoxic agents, with IC50 values of approximately 40 muM.

The [LnL](NO3)3 · nH2O complexes of the series of all lanthanide(III) ions, except radioactive Pm, with the meso-type hexaazamacrocycle L, derived from racemic trans-1,2-diaminocyclohexane and 2,6-diformylpyridine, have been synthesised and characterized. The X-ray crystal structures of the isomorphic La(III) and Sm(III) complexes show that the lanthanide(III) ions are coordinated by six nitrogen atoms of the relatively flat macrocycle L as well as by two axial bidentate nitrate anions and methanol molecule. The complexes have been characterised by NMR spectroscopy and mass spectrometry. 1H NMR signals of the Ce+3, Pr+3, Nd+3, Eu+3 and Yb+3 complexes have been assigned on the basis of the COSY and HMQC spectra, and for the remaining lanthanide complexes the signals were assigned on the basis of linewidths analysis. The paramagnetic shifts of the series of lanthanide complexes [LnL](NO3)3 · nH2O have been analysed using both crystal-field dependent and independent methods. The results of this analysis indicate a change of coordination number along the series of Ln(III) complexes. The properties and stability of the lanthanide(III) complexes of the macrocycle L have been compared with those of the isomeric chiral macrocycle L1.

Synthetic Route of 1436-59-5, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 1436-59-5, Name is cis-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Short Survey，once mentioned of 1436-59-5

A small difference in diamine bis(phenolato) ligands, namely an additional single methylene unit, directs formation of dinuclear Ti(IV) complexes rather than mononuclear ones as characterized by X-ray crystallography. Varying steric bulk of the ligand affects the coordination number in the dinuclear complexes and the ligand to metal ratio. A ligand with reduced steric bulk leads to a L2Ti2(OiPr)4 type complex featuring two octahedral metal centers bridged only by the two phenolato ligands, whereas a bulky ligand leads to a Ti2(mu-L1)(mu-OiPr)2(OiPr)4 type complex with a single chelating ligand, two bridging isopropoxo ligands, and two terminal isopropoxo groups on each of the two metal centers, which are of trigonal bi-pyramidal geometry.

1436-59-5, Name is cis-Cyclohexane-1,2-diamine, molecular formula is C6H14N2, belongs to chiral-catalyst compound, is a common compound. In a patnet, once mentioned the new application about 1436-59-5, HPLC of Formula: C6H14N2

Six half-sandwich RuII coordination compounds of the general formula [Ru([9]aneS3)(L-L)(L?)][PF6]n {2-7; [9]aneS3 = 1,4,7-trithiacyclononane, L-L = 2,2?- bipyridine (bpy), 1,2-diaminoethane (en), (±)-trans-1,2- diaminocyclohexane (dach), picolinate (pic); L? = pyridine (py), 3-acetylpyridine (3-acpy), imidazole (im); n = 1 or 2, depending on the nature of L-L} were prepared and characterized. If irradiated with blue light (lambda = 400-490 nm) in aqueous solution, they readily dissociate the monodentate L? ligand to generate selectively the corresponding aqua species. The extent and rate of photoinduced ligand release depend primarily on the nature of the chelating ligand (bpy >> en ? dach > pic) and, to a minor extent, on that of the leaving ligand (py > im > 3-acpy). Photolabile compounds 2-5 showed no significant antiproliferative activity against the MDA-MB-231 human mammary carcinoma cell line, both in the dark and upon irradiation with blue light. The clean photodissociation process that characterizes this class of half-sandwich RuII compounds, and the substantial lack of toxicity of the photogenerated Ru aqua species, suggest that they might be suitable for the preparation of “caged” RuII compounds. In the frame of this work, two unexpected dinuclear compounds, namely, [{Ru([9]aneS3)(en)}2(mu-en)][CF 3SO3]4 (9) and [{Ru([9]aneS3)} 2(mu-dach)(mu-CH3O)2][CF3SO 3]2·2CH3OH (10) – both containing rare examples of bridging en and dach ligands – were also isolated and structurally characterized. If irradiated with visible light in aqueous solution, the photolabile RuII half-sandwich coordination compounds [Ru([9]aneS3)(L-L)(L?)]2+ ([9]aneS3 = 1,4,7-trithiacyclononane; L-L = 1,2-diaminoethane, etc.; L? = pyridine, etc.) readily dissociate L? to generate the corresponding aqua species.

The use of the diamine rac-trans-1,2-diaminocyclohexane (LL) as a major component of the solvent system allows the isolation of crystalline silver complexes with higher ratios of LL to silver (up to 4 : 1, compared to the previously obtained 1 : 1 in ethanolic solution). The complexes obtained and crystallographically characterized were (LL)2AgNO3 (1), (LL)3Ag(OAc)(H2O)2 (2) and (LL) 4AgBr(H2O)3 (3). Additionally, the silver-free compounds (LL).(H2O) (4) and (LL)3.HCl (5) were obtained as by-products. Complex 1 is a chain polymer with one bridging and one terminal LL ligand; the chains are homochiral. Complex 2 contains isolated [(LL) 3Ag]+ cations with one chelating and two monodentate ligands. Complex 3 contains dimeric [(LL)2AgBr]2 units; the additional LL molecules are not coordinated to the metal. Compound 5 consists of one diamine with imposed twofold symmetry, one half-protonated diamine in which the acidic hydrogen site is half-occupied (it is involved in a disordered hydrogen bond N-H…N across a twofold axis) and a chloride anion on a twofold axis. In all five structures, the components pack so as to form clearly defined hydrophilic and hydrophobic areas. In the former, classical hydrogen bonds are formed. Except for a few borderline cases of three-center bonds, these are all two-center systems. The appreciable number of these (e. g. 20 for compound 3) renders the layer structures quite complex, but in most cases they can be analyzed in terms of smaller units.

The proton transfer in the intramolecular hydrogen bond in a series of Schiff bases derivatives of aromatic orthohydroxyaldehydes and trans-1,2-diaminocyclohexane has been studied by means of IR, UV-Vis, 1H and 13C NMR spectroscopies. The measurement of deuterium isotope effect on 13C chemical shift suggests that the proton transfer equilibria in both salicylidene moieties are not independent. Substitution of H by D in one hydrogen bond shifts the proton transfer equilibrium in one direction in this moiety, while in the opposite direction in the other.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of cis-Cyclohexane-1,2-diamine, you can also check out more blogs about1436-59-5
