Some of the thermochemical data derived from this study include Ddegree}(Msup minus}}-S) > 103 kcal/mol and Ddegree}(Msup minus}}-SH) = 83 plus minus}9 kcal/mol. Finally, a brief survey of the reactivity of Vsup minus}}, Crsup minus}}, and Mosup minus}} with selected organosulfur compounds is also reported. 79 refs., 3 figs., 7 tabs

kinetic parameters varied little, though the rates of inversion were determined in other solvents. The entropy of activation and the solvent effects together with the presence of coupling between the phosphine-31P and the methine-1H throughout the temperature range of investigation evidence the sulfurinversion without breaking the Pt–S bond.
