The thermal reactions of trichlorosilane (1a) with cyclic alkadienes such as cyclopentadiene (2a), 1, 3-cyclohexadiene (2b), and 1, 4-cyclohexadiene (2c) were studied at temperatures ranging from 170° C to 250° C. In this reaction, the hydrosilylation rate increased as the reaction temperature was raised using an equimolar ratio of 1a to 2a. The reaction of 2a with 1a at 250° C afforded 2-cyclopentenyltrichlorosilane (3a) as the major hydrosilylation ...
