title: Acyl polysilanes: new acyl anion equivalents for additions to electron-deficient alkenes.
abstract: Silenes, generated through thermolysis of acylpolysilanes, add to alpha,beta-unsaturated esters to form 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 acyl anion chemistry of acyl polysilanes.
