Abstract
The catalytic activity of H2PtC16 in the hydrosilylation was evaluated in the presence of sulfide derivatives to clarify the relationship between the sulfide structures and their controllability of the hydrosilylation process. From the study on the hydrosilylation reaction of trimethylvinylsilane with triethylsilane at various temperatures, it was found that the catalytic activity depended upon the substituents on the added sulfide derivatives. In case of disulfide derivatives, the catalytic activity was remarkably suppressed compared with the case of mono sulfide derivatives in observing the same tendency to the model reaction. Effective control of the catalytic activity was shown applicable to the crosslinking reaction of silicone resin.
