UV photolysis of diazo(pentamethyldisilanyl)methyl ketones 1b-d generates acylsilenes (3-oxo-1-sila-1-propenes) 3 as reactive intermediates, which can be trapped by enolizable carbonyl compounds in an ene-type reaction.With non-enolizable carbonyl compounds or ethyl acetate, they undergo a cycloaddition.In contrast to the photolysis in the absence of these carbonyl compounds, a Wolff rearrangement of 1b-d (or the derived carbenes) to silyl ketenes 5b-d is observed as a competitive reaction.
