Abstract
Stabilized bismuthonium ylides, triphenylbismuthonio-4, 4-dimethyl-2, 6-dioxocyclohexane- 1-ide and triphenylbismuthonio-4, 4-dimethyl-2, 6-dioxo-3, 5-dioxan-1-ide, react with aldehydes to afford three types of products; tetraacylcyclopropanes, dihydrofurans, and α, β- unsaturated carbonyl compounds, the relative importance of these depending greatly on the ylides, aldehydes, and reaction conditions employed.
