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.

β¦ Synopsis
The spirophosphorane 4 underwent reaction with a series of benzene-su,?phenic esters 3 to give the corresponding isolable alkoxyphosphoranes. The reactivities of benzenesulphenic esters 3 in this reaction were seen to be dependent on steric hindrance of the R groups. The yields of alkoxyphosphoranes were influenced by the reaction temperature. The probable mechanism was suggested in terms of experimental observations.

The reaction of PhCH 2 C(O)NR 2 /P(O)Cl 3 (R β«Χ‘β¬ alkyl) with diethyl or triethyl phosphite afforded E-vinylphosphonates 3 with high geometrical stereoselectivity and acceptable yields. The reaction with hydridophosphorane 8 gave 10, a novel trisphosphoranylphosphine oxide that can be reduced to the
