Thermodynamic and kinetic studies of reactions of thiols, disulfides, sulfur, and hydrogen sulfide

Abstract

Kinetic and thermodynamic investigations of reactions of thiols, disulfides, hydrogen sulfide and sulfur with complexes of Cr, Mo, and W were done as the chemistry of transition metal complexes is important to a number of industrial processes. The reaction mechanism was influenced by the strength of the sulfur-sulfur or sulfur-hydrogen bond to be broken. The mechanism was also affected by ligand donor ability of the sulfur compound. The enthalpies of reaction with chalcogen donors [Y = S, Se, Te] were measured for a range of R 3E complexes [E = P, As, Sb]. The reaction of hydrogen sulfide with the radical species was much faster than analogous reactions of thiols. Initial oxidative addition of one sulfur-hydrogen bond was observed. The mechanism of this reaction followed two pathways. This research was supported by the Petroleum Research Fund.
