Acid chlorides alkenyl silanes

Reaction of alkenyl silanes with acid chlorides is catalyzed by aluminum chloride or stannic chloride.126... 

E)-l-Trimethylsilyl-l-alkenes are available by chloroplatinic acid catalysed hydrosilylation of 1-alkynes. These vinyl silanes react with dichloromethyl methyl ether in the presence of titanium(iv) chloride at low temperature to give a/S-unsaturated aldehydes. Alkenyl silanes with the silyl group in a non-terminal position also give the corresponding a/8-unsaturated aldehyde (Scheme 50). " ...
