The reaction of PhCH2C(O)NR2/P(O)Cl3 with phosphites and hydridophosphorane

The reaction of PhCH2C(O)NR2/P(O)Cl3 (R = 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 corresponding phosphine 14. © 2000 John Wiley & Sons, Inc.
