In recent years, the synthetic applications of multifunctional heteroallenes1 have been widely investigated. In spite of extensive developments in the chemistry of modified ketenes and isocyanates, 2 little attention has been paid to the uses of ketenimines. 3 From a synthetic point of view it was of interest to synthesize a ketenimine bearing a phosphoryl group4 as an eliminatable substituent. Previously we reported5 a facile preparation of a C-phosphonoketenimine6 which acts as a novel annelation reagent. In this paper we report further investigation of these reactions and their synthetic utility for the prepa-ration of heterocycles.
