Gas phase reactions of 1,1-dimethylsilabutadiene

Article abstract of DOI:10.1016/0022-328X(89)85136-8

Pyrolysis of 1,1-dimethyl-1-siletene at 363 deg C in a static reaction vessel produces three major products which are formal dimers of the starting material or the reactive isomer, the siladiene.Reactions with ethylene, propene, vinyltrimethylsilane and butadiene have been examined.Mechanisms leading to the Si2C10H20 products are discussed.The influence of temperature and concentration of coreactant on competing reaction pathways is interpreted.
