Synthesis, Structure, and Isomerization of Diazaphosphiridine OxidesHerrn Professor Joseph Grobe zum 60. Geburtstag gewidmet.The 1,2-Bis(alkyl)iminophosphane, Et3C - P=N - tBu (1), reacts with nitroso compounds, RNO (R=tBu, Ph), to form the diazaphosphiridine oxides, Et3C - YYP(=O) - NtBu - NYYR, 4a, b. While 4a (R=tBu) is thermally stable, 4b (R=Ph) isomerizes with formation of the benzodiazaphosphole oxide Et3C - YYP(= O) - NH - C6H4 - NYYtBu (5). The corresponding phospholimine Et3C - YYP(=NtBu) - NH - C6H4 - NYYtBu (7) has been obtained from 1 and azobenzene. The three-membered phosphorus heterocycle 4a has been characterized by X-ray structure analysis, which reveales some remarkable features.
