α-Ketoacylsilanes may be prepared by the sequential osmiumtetroxide catalysed dihydroxylation and Swern oxidation of -vinylsilanes. Addition of nucleophiles to α-ketoacylsilanes occurs to give products arising exclusively from reactions at the silicon-bearing carbonyl group.

A series of silylketones has been prepared by appropriate manipulation of ⇌-silylated allenol ethers. Among the compounds prepared were alkenyl, alkynyl and acyl silylketones. The spectroscopic properties of representative members of these classes of compounds have been measured, and some of their chemical reactions studied Diels-Alder cycloadditions of vinyl and alkynyl silylketones proceed smoothly

The reaction of dimethyldioxirane with several alkynes gives products which are conveniently rationalized by postulating the intermediacy of oxirenes and oxocarbenes. The latter serve as precursors to H atom or methyl group migration products, as well as to cyclopropane insertion products in some cases. Alkenes, derived from some of these carbene reactions, are partially converted to epoxides.
