摘要

In situ generated iminophosphoranes 1 react with dicarbonyl dihalides 2a-b and 3a-c to give known or new nitrogen heterocycles. The proposed mechanisms involve elimination of either triphenyl-phosphine oxide or dichlorotriphenylphosphorane depending upon both the iminophosphorane and the dicarbonyl compound.
