Abstract

Abstract The aldimine n BuN= CH i Pr and phosphorus trichloride react to give phosphorus (III) amides in a 1: 1 and 2: 1 molar ratio. An imine-enamine tautomerism is proposed. In a [4+ 1] cycloaddition reaction diacetyl-(Nn-butyl) diimine and λ3σ3P-species, RPCl2 or EtOPCl2, form 1, 2, 3λ5σ4-diazaphospholenes1. The same diimine and (Et2N) 2 PCl is furnishing annellated azaphospholenes1. A 1, 3, 4λ5 σ4-diazaphospholanium is formed ...
