Abstract
DFT calculations (M06, PBE0/Def2-TZVP) of coordination compounds used in reactions of selective oxidation of thiols to disulfides were performed. Primary active centers of the catalysts are polynuclear scaffolds {L2M(μ-OH)2ML2}2+ and {L2M(μ-OH)2M′(μ-OH)2ML2}2+ (M = CuI, CuII, PdII; M' = CuII; L = NH3). CuII ions in combination with PdII ions are capable of formation of polynuclear active center {PdII(μ-OH)2CuII(μ-OH)2PdII}2+ bringing together a large number of mutually oriented RS– groups and thus affecting the rate of formation of disulfide R2S2.
