cyclobutanes and silylsubstituted cyclopropanes in moderate yields. Upon Si−C bond oxidation the cyclopropanes are converted directly to 1,4-dicarbonyl compounds, thus demonstrating the formal acylanion chemistry of acyl polysilanes.

The elucidation of a robust and reliable sequence for the generation of highly reactive transient silenes from simple aldehydes is described. The key step involves a silyl-modified Peterson olefination which critically depends on the presence of a sub-stoichiometric amount of soluble lithium salts (LiBr).
