β-Ketoallylsilanes are synthesized by the Horner−Emmons reaction starting from novel silylated ketophosphonates and various aldehydes. The reactions of β-ketoallylsilanes with NsONHCO2Et and CaO produce α-methylene-N-(ethoxycarbonyl)-β-amino ketones through the ring opening of the intermediate aziridine, which is favored by the presence of the trimethylsilyl group. With chiral β-ketoallylsilanes we

Allylsilanes bearing the various functionalities were prepared from the palladium-catalyzed cross-coupling reactions of 2-trimethylstannyl-3-trimethylsilylpropene with acid chlorides and with aryl halides.
