Synthesis, structure, magnetic properties, and catecholase-like activity of a phenoxo bridged dinuclear cobalt(II) complex

A dinuclear cobalt complex Co2L2 (H2L = N,N'-bis(salicylidene)-2,2′-ethylenedianiline) have been synthesized and characterized. X-ray crystallography found that Co2L2 contains a planar Co2O2 core where two Co(II) ions are bridged by two phenoxo ligands with Co-Co distance of 3.221 ? and the coordination geometry of each cobalt(II) ion is a distorted trigonal bipyramid. The magnetic susceptibility measurements revealed that both Co(II) ions are in low-spin (S = 1/2) states and two Co(II) spin centers are antiferromagnetically coupled with the exchange coupling constant of J = ?45 cm?1. Co2L2 showed catecholase-like activity when 3,5-di-tert-butylcatechol (3,5-H2dtbc) was treated with Co2L2 in the presence of O2 and NaOH with the turnover number of kcat = 803 h?1. Electron paramagnetic resonance (EPR) on the reaction mixture observed a key reaction intermediates, 3,5-di-tert-butyl-1,2-benzosemiquinonate anion radical (3,5-dtsq[rad]?) bound to Co(III)-center. This is the first time observation of Co(III)-3,5-dtsq[rad]? intermediate during the oxidation of 3,5-H2dtbc by a dicobalt(II/II) complex.

Vanadium(III) phenoxyimine complexes for ethylene or ε-caprolactone polymerization: Mononuclear versus binuclear pre-catalysts

The mononuclear {[C6H4NCH(ArO)]2VCl(THF)} (Ar = 2,4-t-Bu2C6H2 (1), Ar = C 6H4 (2)), {O[C6H4NCH(ArO)] 2}VCl(THF) (Ar = 2,4-t-Bu2C6H2 (3), Ar = C6H4 (4)) and the binuclear vanadium(iii) complexes {[C6H4NCH(ArO)]VCl2(THF)2} 2(μ-CH2CH2) (Ar = 2,4-t-Bu2C 6H2 (5), Ar = C6H4 (6)), have been synthesized and fully characterized. The compounds [C6H 5NCH(ArO)]VCl2(THF)2 (Ar = 2,4-t-Bu 2C6H2 (7), Ar = C6H4 (8)), [2,4,6-Me3-C6H2NCH(ArO)]VCl2 (Ar = 2,4-t-Bu2C6H2 (9), Ar = C 6H4 (10)) and [2,6-i-Pr2-C6H 3NCH(ArO)]VCl2(THF)2 (Ar = 2,4-t-Bu 2C6H2 (11), Ar = C6H4 (12)), {μ-CH2CH2[NCH(C6H4O)] 2VCl(THF)} (14) and {C6H4[NCH(C 6H4O)]2VCl(THF)} (15) were synthesized for comparative polymerization studies. The dizwitterionic compound [2,6-i-Pr 2-C6H3N+(H)CH(C6H 4O)]2VCl2O (13) was also isolated, and presumably formed via a fortuitous hydrolysis reaction. The complexes 2, 5 and 13 have been structurally characterized; the molecular structure of the parent ligand (L5) in 5 is also reported. All complexes have been screened for ethylene as well as ε-caprolactone polymerization, and results are compared against those for known related mono- and bi-nuclear counterparts to evaluate for possible cooperative effects. The compounds 10 and 12 have been supported on modified SiO2, analysed by XPS and subjected to homo-polymerization (ethylene) and co-polymerization (1-hexene and ethylene) studies.
