The photolyses and thermolyses of the cc,l(-epoxy silyl ketones 5 and 6 are described. On n,n\*-excitation, the silyl ketones 5 and 6 were transformed to the ketone 7 and the ketene 8 in quantitative yield. The formation of 8 may be explained by initial cleavage of the C(cx-0 bond and subsequent C(l
