Triphenylbismuthonio-4,4-dimethyl-2,6-dioxocyclohexane-1-ide and Triphenylbismuthonio-4,4-dimethyl-2,6-dioxo-3,5-dioxan-1-ide. Preparation and Properties of the Stable Bismuthonium Ylides

Article abstract of DOI:10.1246/cl.1988.847

The title two bismuthonium ylides were obtained in pure form and their reactions with some electrophiles were studied.In contrast with stable ylides of arsenic and antimony, these bismuthonium ylides readily react sith aldehydes and isothiocyanates but th
