β¦ Synopsis
Reaction of hydridophosphorane 1 with nucleophilic reagents 2 and tetrachloromethane in the presence of triethylamine, according to the Atherton-Todd reaction methodology leads ultimately to the formation of phosphoranes 3 in good yields. A probabLe mechanism has been suggested in terms of experimental obsewations.

Reactions of hydridophosphorane 3 with Vilsmeier reagents, HCONR 1 R 2 /POCl 3 , afford novel N,N-disubstituted amino bisphosphoranyl methanes4. The formation of 4 might occur via the intermediate 5, which then reacts further with excess 3.
