An effective cis-β-octahedral Mn(iii) SALPN catalyst for the Mukaiyama-Isayama hydration of α,β-unsaturated esters

Two cis-β-MnIIISALPN catalysts were synthesised and tested in the Mukaiyama-Isayama hydration of α,β-unsaturated esters. The MnIIIEtOSALPN(acac) complex 7 is the most active and catalyses hydration with little or no detectable undesired alkene reduction. This catalyst is superior for alkene hydration compared to the originally reported Mn(dpm)3 catalyst.

Synthesis, structure and magnetic property of a dinuclear cobalt(II/III) complex with a reduced Schiff base ligand

A dinuclear mixed valence cobalt(II/III) complex, [(N3)CoIIIL(μ-CH3COO)CoII(N3)]?CH3OH with a N2O4 donor compartmental reduced Schiff base ligand, H2L [(1,3-propanediyl)bis(iminomethylene)bis(6-ethoxyphenol)], has been synthesized and characterized by spectral and elemental analyses. Cobalt(III) is placed in the inner N2O2 compartment whereas cobalt(II) is present in the outer O4 compartment of the ligand. Structure of the complex is confirmed by single crystal X-ray crystallography. The magnetic susceptibility measurement confirms that the complex belongs to localized class-I mixed valence system with isolated S = 3/2 ion and shows Curie-Weiss paramagnetism.

Sterically-controlled nuclearity in new copper(II) complexes with di-compartmental ligands: Formation of antiferromagnetically coupled angular trimer and mononuclear inclusion complex

Two new copper(II) complexes, [Cu3(L1)2(H2O)2](ClO4)2 (1) and [CuL2? (H2O)] (2) have been derived from two di-compartmental Schiff base ligands H2/sub

Formation of a water-mediated assembly of two neutral copper(II) Schiff base fragments with a Cu2(NCS)4 moiety: Exploration of non-covalent C-H?π(bimetallo ring) interactions

A water molecule is encapsulated in a dimeric assembly of a copper(ii) Schiff base complex with a Cu2(NCS)4 moiety. The structure has been confirmed by single crystal X-ray diffraction analysis. Thermogravimetric analysis has been performed to check the stability of the enclathrated water molecule. This theoretical study is devoted to analyzing the stabilization of the H2O molecule in the cavity generated by the formation of the supramolecular dimer of the copper(ii) Schiff base moiety in the solid state. The Cu2(NCS)4 moiety exists as a bimetallic eight-membered ring, which behaves as a π-system establishing C-H?π interactions with two neighbouring copper(ii) Schiff base moieties. The molecular electrostatic potential (MEP) surface of the complex has been computed to rationalize the interaction from an electrostatic point of view.

Antihyperglycemic and neuroprotective effects of one novel Cu-Zn SOD mimetic

Increasing evidence supports that OS plays important roles in diabetes mellitus and cerebral ischemia. This suggests that recovering an impaired endogenous superoxide dismutase (SOD) enzyme system induced by OS with a mimetic would be beneficial and protective for these diseases. In present study, one nonpeptidyl small molecular weight compound (D34) was synthesized. Its SOD mimetic activity and the potential therapeutic actions were also evaluated both in vivo and in vitro. The in vitro nitro blue tetrazolium (NBT) assay indicated that D34 presents an SOD mimetic activity. D34 (20 μmol/kg) exhibited significant antihyperglycemic activity in alloxan-diabetic mice. D34 could also ameliorate the cerebral neuronal death in hippocampus of global cerebral ischemia mice. Furthermore, the D34 treatment significantly decreased malondialdehyde (MDA) contents and increased SOD activities in brains or livers of diabetes mice or cerebral ischemic mice. In conclusion, these preliminary findings support that D34 exhibits SOD mimetic activity and possesses significant antihyperglycemic and neuroprotective effects.

Estimation of conventional C-H?π (arene), unconventional C-H?π (chelate) and C-H?π (thiocyanate) interactions in hetero-nuclear nickel(II)-cadmium(II) complexes with a compartmental Schiff base

Three new heteronuclear nickel(ii)/cadmium(ii) complexes, [(SCN)(Cl)Cd(L)Ni(DMF)2] (1), [(SCN)(CH3CO2)Cd(L)Ni(CH3OH)2] (2) and [(SCN)(Cl)Cd(L)Ni(NH2CH2CH2CH2NH2)]n (3) {where H2L = N,N′-bis(3-ethoxy-salicylidene)propane-1,3-diamine is a N2O4 compartmental Schiff base}, have been synthesized and characterized. The structures of the complexes have been confirmed by single crystal X-ray diffraction studies. In each complex, nickel(ii) is placed in the inner N2O2 environment and cadmium(ii) is placed in the outer O4 compartment of the compartmental Schiff base. Furthermore, the importance of unconventional C-H?π (chelate) interactions in the solid state of both complexes and C-H?π (thiocyanate) interaction in complex 2 has been described by means of DFT and MEP calculations and characterized using NCI plots. All complexes show photoluminescence at room temperature upon irradiation by ultraviolet light. The lifetimes of excited states are in the range of 2-6 ns.
