✦ Synopsis

The decomposition kinetics of ethylsilane under shock tube conditions (P, ca. 3100 torr, T = 1080-1245 K), both in the absence and presence of silylene trapping agents (butadiene and acetylene) are reported. Arrhenius parameters under maximum butadiene inhibition are: log K(C,H,SiH,) = 15.14-64,769 2 1433 ca1/2.303 R T log K(C,H,SiD,) = 15.29-66,206 ? 1414/2.303 RT. The uninhibited reaction is subject to silylene induced decomposition (63% lowest T -24% highest 2'). Major reaction products are ethylene and hydrogen, consistent with two dominant primary dissociation reactions:
