Abstract
Tris(dialkylamino)phosphines IIIa and IIIb react with furfurylidenemalonitrile (Ia) and its thiophene analogue Ib to give a mixture of 1 : 1 adducts IV and V. Compounds IV have aminophosphonium dipolar ion structure, while compounds V are the ylide forms. The ratio of the products depends on the reaction conditions. Some reactions of IV and V are described.
