Synthesis of Bis(phosphinoyl)amines and Phosphinoyl–Phosphorylamines by the N‐Phosphinoylation and N‐Phosphorylation of 1‐Alkylamino‐2,5‐dihydro‐1H‐phosphole 1‐Oxides

The N‐phosphinoylation and N‐phosphorylation reaction of 1‐alkylamino‐2,5‐dihydro‐1H‐phosphole 1‐oxides with diphenylphosphinoyl chloride and diethylphosphoryl chloride/diphenylphosphoryl chloride afforded new families of compounds comprising bis(phosphinoyl)amines and phosphinoyl‐phosphorylamines, respectively, whose stereostructures were elucidated by B3LYP/6‐31G(d,p) and B3LYP/6‐31G++(d,p) calculations. The P analogues of the mixed imides may be valuable intermediates in syntheses.
