(Chemical Equation Presented) The s-BuLi complex of a cyclohexane-derived diamine is as efficient as s-BuLi/(-)-sparteine for the asymmetric deprotonation of N-Boc pyrrolidine. This is the first example of high enantioselectivity using a non-sparteine-like diamine in such reactions. The ( S, S)-diamine is a useful (+)-sparteine surrogate and was utilized in short syntheses of (-)-indolizidine 167B and an intermediate for the synthesis of the CCK antagonist (+)-RP 66803.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 1436-59-5. In my other articles, you can also check out more blogs about 1436-59-5

Electric Literature of 1436-59-5. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 1436-59-5, Name is cis-Cyclohexane-1,2-diamine. In a document type is Article, introducing its new discovery.

Reaction of potassium ferricyanide with a mixture of nickel(II) chloride hexahydrate and trans-1,2-diaminocyclohexane (L) produces both a ferrocyanide ([NiIIL2]2[FeII(CN) 6] · 5H2O (1)) and a ferricyanide ([NiII(L)2]3[FeIII(CN) 6]2 · 2H2O (2)) compound. Clearly, the formation of 1 is accompanied by the reduction of ferricyanide to ferrocyanide. Interestingly, the relative amounts of the formation of 1 and 2 depends on the nickel(II):diamine ratio and the volume of the reaction mixture. It has been established from spectrophotometric titration that trans-1,2-diaminocyclohexane is responsible for the reduction of [Fe(CN)6]3- to [Fe(CN)6]4-. The ferrocyanide analogue, 1, can also be prepared by mixing potassium ferrocyanide with the nickel(II)-diamine solution. Among the six cyanides of each hexacyanoferrate(II), four coordinate to four different nickel(II) centers to form cyano-bridged two-dimensional square grids. The remaining two cyanides form strong hydrogen bonds with two hydrogens of one water of crystallization to result in squares, which can be considered as appended to the two-dimensional grids. The hydrogen bonds involving the hydrogens of amine groups of one 2D grid and the oxygens forming the appended squares of another 2D grid generate the third dimension of the structure. Variable-temperature (2-300 K) magnetic susceptibility measurements reveal that the nickel(II) centers in 1 are practically non-correlated.

A novel class of 13-membered tetraaza rings containing dipyridylmethaneamide units was obtained by condensation of 1,2-diamines with 1,1-bis<6-(chloroformyl)-2-pyridyl>-1-methoxypropane.By use of trans-1,2-diaminocyclohexane, a chiral macrocyclic amide was obtained, while the cis isomer afforded two diastereomeric pseudochiral compounds.The chiral ligand yielded a square-planar complex with Ni(II) by loss of the amide protons, with the chirality close to the metal center.The structures of the two macrocyclic dipyridylmethane amides derived from (R,R)- and (R,S)-diaminocycohexane (5a and 6a, respectively), and that of 1,1-bis(6-carboxy-2-pyridyl)-1-methoxypropane (1) were studied by X-ray diffraction.In the crystal of 1-monohydrate, the dipyridylmethane moiety adopts an anti conformation with the two aromatic rings nearly perpendicular to one another.The crystal of 5a and that of 6a contain two and three crystallographically independent molecules, respectively.These five macrocycles are very similar in their overall bowllike shape but exhibit minor conformational differences. 1H NMR studies demonstrate that similar conformations are maintained in solution.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1436-59-5, Name is cis-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 1436-59-5, Recommanded Product: 1436-59-5

A new procedure for the efficient synthesis of 1,4-piperazinones, 1,4-thiazinones and 1,4-diazepinones is presented. The reaction is based on a ring chain transformation of gamma-keto-delta-crotonolactones induced by 1,2- or 1,3-diamino- (or thiamino-) binucleophiles. The reaction sequence of this transformation is also discussed.

The new polyoxovanadate {[Fe(C6H14N2) 2]3[V15Sb6O42(H 2O)]}·8H2O (1) was obtained under solvothermal conditions using the amine that acts at the same time as the ligand, solvent, and reducing agent. The central structural motif of 1, [V15Sb 6O42(H2O)]6-, is related to the {V18O42}-archetype cluster by replacing three VO 5 square pyramids with three O2Sb-O-SbO2 moieties. Every [V15Sb6O42(H 2O)]6- cluster anion is expanded by six FeN 4O2 octahedra, thus generating a rare three-dimensional network with differently sized pores hosting the crystal water molecules. In 1, two [V15Sb6O42(H2O)]6- cluster anions with different orientations coexist. According to bond-valence-sum calculations, the anionic cluster can be formulated as [V IV15SbIII6O42(H 2O)]6-, i.e., in line with the valence states of all other known {V15Sb6} clusters. The optical band gap of 1 was determined as 2.47 eV. Investigation of the magnetic behavior indicates dominating ferromagnetic exchange interactions between the V4+ centers of the cluster and the Fe2+ d6 cations.

Nucleophilic ring opening of bis- and tris(1-oxa-3,5-diazinium) salts 1 with n-propylamine leads to the bis- and tris-(armed) oligonitrile derivatives 3 and 8 with secondary amino groups in the side chain. Alternatively, treatment of simple 1-oxa-3,5-diazinium salts 2 with primary and secondary di- and triamines offers a convenient pathway for the synthesis of bis- and tris(armed) oligonitriles 4, 5 and 7. 2,6-Diaminopyridine furnishes the new pincer-type ligand 6 upon reaction with 1-oxa-3,5-diazinium salt 2a. Multivalent oligonitriles 4, 6, 7 and 8 containing secondary amino groups are able to form intra- and intermolecular hydrogen bonds in the solid state as detected by X-ray crystallography. The oligonitriles 3a,b, 4b,d,h, 6 and 7a form coordination complexes with various ZnII, CuII, CoII, NiII and PdII salts acting as bidentate ligands to give six-membered chelates of 1:1, 1:2 and 2:2 ligand/metal ion ratios. More complex structures are obtained from pincer ligand 6 with PdCl2 [compound 6·(PdCl2)2] and from the tridentate ligand 7a in reactions with Ni(ClO4)2 (compound 9). All new complexes were characterized by X-ray crystallography. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

The structures of the title complexes, (C6H15N 2)2[MoS4], (I), and (C6H 16N2)[MoS4], (II), can be described as consisting of discrete tetrahedral [MoS4]2- dianions that are linked to the organic ammonium cations via weak hydrogen-bonding interactions. The asymmetric unit of (I) consists of a single (±)-trans-2-aminocyclohexylammonium cation in a general position and an [MoS4]2- anion located on a twofold axis, while in (II), two crystallographically independent trans-cyclohexane-1,4-diammonium cations located on centres of inversion and one [MoS4]2- anion in a general position are found. The differing dispositions of the amine functionalities in the organic cations in the title complexes lead to different crystal packing arrangements in (I) and (II).

A document type is Article, introducing its new discovery.

Reaction Of Ag2CO3 with four methyl-substituted derivatives of benzoic acid afforded silver benzoates; no additional anions are involved in these solids. One of the silver carboxylates was studied by X-ray diffraction: in the crystal, silver 3,5-dimethylbenzoate monohydrate consists of carboxylato-bridged discrete dinuclear molecules with a short Ag-Ag separation of 2.7719(5) A and one weakly bonded hydrate water molecule per cation. The binary silver carboxylates were combined with either racemic or enantiopure rrans-1,2-diaminocyclohexane and resulted in four homochiral and four heterochiral crystalline solids. All eight structures feature cationic chain polymers, carboxylate anions and hydrate water. In three of the solids derived from the racemic ligand, the individual cationic chains are homochiral. In all structures, the primary coordination of the Ag(I) centers by nitrogen is essentially linear. Despite the chemical similarity in the anions, the backbone of the polymers proved to be conformationally soft with variable Ag-N-C-C torsion angles. In the resulting structures, the diamine ligand may bridge two cations in a wide distance range between ca. 3.0 and ca. 7.2 A. Both the chirality of the frans-1,2-diaminocyclohexane ligand and the substitution pattern of the benzoate anion have strong impact on the nature of secondary interactions perpendicular to the polymer strands: either weak coordination by carboxylato or hydrate water oxygen atoms or argentophilic interactions are encountered. The Ag-Ag contacts increase the dimensionality of the solids from chain polymers to layer structures.
