| Abstract: | Abstract The aldimine nBuN=CHiPr 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-(N-n-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 from a λ3σ3 -phosphenium and iPrN=CMe2 2. Phosphorus(III) amides P(NR2)3 (R= Me, Et) and O-trimethylsilylated diacetyldioxime give rise to yield the first monocyclic pentaazaphosphoranes. |
