Development and application of latent hydrosilylation catalyst [6]: control of activity of platinum catalyst by isocyanide derivatives on the crosslinking of silicone resin via hydrosilylation

Quite effective nature of isocyanides to control the curing reaction of silicone resin via the Ptcatalyzed hydrosilylation process is described. In the presence of the isocuanides, the curing reaction of the silicone resin by H2PtCl6 did not occur at ambient temperature, while the lack of the isocyanide systems conducts the smooth curing, indicating that the present systems serve as a thermal latent catalyst for silicone resin. The curing temperature was controllable by the character and the concentration of the isocyanides employed.
