Friedel-Crafts Reactions of Some Vinyisilanes

Fleming, Ian,Pearce, Andrew

, p. 2485 - 2489 (2007/10/02)

Substituted cyclohexenylsilanes (2), (5), (9), and (13) undergo Friedel-Crafts reactions to give substitution products, site-selectively at the carbon atom carrying the trimethylsilyl group. β-Trimethylsilylstyrene (17) similary gives more substitution in Friedel-Crafts reactions with benzoyl chloride and with phenylacetyl chloride than styrene itself.The syntheses of the silanes are reported, and some limitations of the idea identified.
