Abstract: | Reactions of hydridophosphorane 3 with Vilsmeier reagents, HCONR1R2/POCl3, afford novel N,N-disubstituted amino bisphosphoranyl methanes 4 . The formation of 4 might occur via the intermediate 5 , which then reacts further with excess 3 . © 1997 John Wiley & Sons, Inc. Heteroatom Chem 8 : 517–520, 1997 |
