Di-Schiff base ligand, N,N’-bis(2-pyridylmethylidene)-trans-1,2-diiminocyclohexane (trans-BPIC), having sufficient hydrophobicity acts as neutral bidentate ligand in ion-pair extraction of divalent metal cations into nitrobenzene with picrate anion. In present study, the effect of steric restriction by chemical structure around imine-N donor atoms in trans-BPIC analogs on their complexation with divalent metal cations in ion-pair extraction was investigated by using N,N’-bis(2-pyridylmethylidene)-cis-1,2-diiminocyclohexane (cis-BPIC) and N,N’-bis(2-pyridylmethylidene)-o-diiminobenezene (BPIB). The former was used to observe the effect by geometrical restriction and the latter was by conjugate restriction. In BPIB – NaPic system, the higher extractability was obtained than those in cis- and trans-BPIC systems, and this result seems to be led by the increase of steric distortion originated from conformational restriction. Namely, it is considered that the extractability can be controlled by steric restriction on the complexation.

The preparation of tetrakis(trimethysilyl)hypophosphate, P 2O2(OTMS)4 (TMS = SiMe3), which is easily obtained from cheap starting materials, is reported. Reaction with protic substrates (H2O, alcohols) proceeds under stepwise cleavage of silylethers, ROTMS, and formation of hypophosphoric acid, P2O 2(OH)4. Amines in the presence of molecular sieves lead to desilylation and formation of ammonium salts of the [P2O 2(OTMS)2(O-)2] dianion. On cotton fabrics, P2O2(OTMS)4 hydrolyzes to give P 2O2(OH)4 within about 1 h when exposed to air, and this compound acts as an efficient flame retardant (limiting oxygen index >26%) even at low loadings (P content <3%).

The chiral triplesalen ligand H6chand provides three chiral salen ligand compartments in a meta-phenylene arrangement by a phloroglucinol backbone. The two diastereomeric versions H6chand RR and H 6chand rac have been used to synthesize the enantiomerically pure chiral complex [(FeCl)3-(chand RR)] (3 RR) and the racemic complex [(FeCl)3(chand rac)] (3 rac). The molecular structure of the free ligand H6chand rac exhibits at the terminal donor sides the O-protonated phenol-imine tautomer and at the central donor sides the N-protonated keto-enamine tautomer. The trinuclear complexes are comprised of five-coordinate square-pyramidal Fe III ions with a chloride at the axial positions. The crystal structure of 3 rac exhibits collinear chiral channels of ?11 A in diameter making up 33.6 % of the volume of the crystals, whereas the crystal structure of 3 RR exhibits voids of 560 A 3. Moessbauer spectroscopy demonstrates the presence of Fe III high-spin ions. UV/Vis spectroscopy is in accordance with a large delocalized system in the central backbone evidenced by strong low-energy shifts of the imine pi-pi * transitions relative to that of the terminal units. Magnetic measurements reveal weak intramolecular exchange interactions but strong magnetic anisotropies of the Fe III ions. Complexes 3 rac and 3 RR are good catalysts for the sulfoxidation of sulfides providing very good yields and high selectivities with 3 RR being enantioselective. A comparison of 3 RR and [FeCl-(salen’)] provides higher yields and selectivities but lower enantiomeric excess values (ee values) for 3 RR relative to [FeCl(salen’)]. The low ee values of 3 RR appeared to be connected to a strong ligand folding in 3 RR, opening access to the catalytically active high-valent Fe-O species. The higher selectivity is assigned to a cooperative stabilization of the catalytically active high-valent Fe-O species through the phloroglucinol backbone in the trinuclear complexes.

An asymmetric aminocatalytic activation strategy to obtain enantioenriched cyclobutanes through [2 + 2] photocycloaddition under visible light irradiation is presented. This metal-free process does not require the use of any external photocatalyst, as it is catalyzed by a simple diamine which, upon condensation with an enone substrate, forms an iminium ion intermediate that absorbs in the visible light region. The direct excitation of such an intermediate leads to a charge transfer (CT) excited state that unlocks a stereocontrolled intermolecular photocycloaddition with good enantiomeric and diastereoisomeric ratios and high yields. Finally, DFT calculations and experiments were performed to support the charge transfer behavior and the mechanistic proposal.

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.Computed Properties of C6H14N2, you can also check out more blogs about21436-03-3

Two new isomeric bis(trans-fused cyclohexano) substituted 1,4,7,10,13-pentaazacyclopentadecane ligands and their Mn(II) complexes, 3 and 4, have been synthesized, and their activity as superoxide dismutase (SOD) catalysts has been studied. Complex 3 is an excellent SOD catalyst with a second-order rate constant at pH = 7.4 of 1.2 x 10+8 M-1 s-1. In contrast, the isomeric complex 4 has virtually no detectable catalytic SOD activity, implying the need to understand the effect that the position, number, and stereochemistry of substituents exert on the catalytic rate. The crystal structure of the complex 4 was determined and reveals that the Mn(II) ion is coordinated in a pentagonal bipyramid array of the five nitrogens of the macrocyclic ligand and capped by two trans-chloro ligands. Crystal data for MnC18H37Cl2N5 are as follows: triclinic at 20C, space group P1–C(i)2 (no. 2); a = 9.746(3) A, b = 12.631(6) A, c = 11.311(5) A; alpha = 73.14(4), beta = 76.39(3), gamma = 79.98(3), V = 1287(1) A3, and Z = 2 (rho(calc))1 = 1.279 g/cm3; mu(a) Mo K(alpha)= 6.23 mm-1). Mechanistic studies with the complex 3 and the pentamethyl susbstituted complex, 5, including D2O rate studies, are reported and are consistent with the existence of two pathways for the rate-determining electron-transfer from Mn(II) to superoxide: (1) hydrogen atom transfer from a bound water on Mn(II) to HO2. to yield a Mn(III) hydroxo intermediate and (2) the dissociative pathway in which superoxide anion binds to a vacant coordination site on Mn(II) followed by protonation/oxidation to yield a Mn(III)hydroperoxo species. Subsequent reduction of the intermediate Mn(III) with superoxide anion completes the catalytic cycle. Substituent effects on the rates and relative contribution of the two pathways to the overall rate of SOD activity is ascribed to the propensity of the ligand to fold around Mn(II) forming a pseudo-octahedral complex similar in geometry to the oxidized Mn(III) complex. Folding of the pentaaza macrocyclic ligand is confirmed as a relevant structural motif for this series of Mn(II) complexes by the X-ray structure determination of the bis(nitrate) derivative of 1, [Mn(C10H25N5)NO3]NO3, which reveals a six-coordinate structure with a folded conformation of the macrocyclic ligand. Crystal data for [Mn(C10H25N5)NO3]NO3: orthorhombic at -100C, space group P212121; a = 9.457(2) A, b = 12.758(2) A, c = 13.834(2) A, V = 1669.1(5) A3, and Z = 4 (rho(calc)1 = 1.549 g/cm3).
