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 R3E 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.
