Kinetic studies have been conducted for the reactions of ethoxytrimethylsilane with benzenesulfinyl chloride and aryloxytrimethylsilane with methanesulfinyl chloride. Both the reactions were found to obey second order rate equation. A clear negative ρ value was observed for the reaction of aryloxytrimethylsilane. The solvent effects suggested that both the two reactions were quite similar in their mechanisms. Nucleophilic addition of silyloxygen atom to sulfinyl group has been suggested for these two reactions.
