Acylsilanes are prepared in good yields by the reaction of acid chlorides (or anhydrides) with LiAl(SiMe3)4 or LiMeAl(SiMe3)3 in the presence of a catalytic amount of CuCN.

Treatment of 1-trimethylsilylcyclopropyllithium derivatives with dichloromethyl methyl ether affords the corresponding newcyclopropylsilylketones in moderate yield. This reaction involves the intramolecular 1,2-silicon shift from carbon to carbon.

The reaction of a series of cyclopropyl trimethylsilyl ketones with acids proceeds under milder conditions compared to that of their carbonanalogs to give either the ring opening products, 3-chloropropyl trimethylsilyl ketones, or the ringenlargement products, 2-trimethylsilyl-4,5-dihydrofuran derivatives.
