acetylenic compounds 5 yield phosphoranes that spontaneously gives ring closure with one of the imidyl carbonyl groups. If this imidyl substituent is an unsymmetrically substituted succinimide, the carbonyl group with less steric hindrance undergoes cyclization. Phthalimidyliminophosphoranes react with some α-halonitriles (i) on the positive halogen if the nitrile group is stericallyhindered (halonitriles
