Abstract

Diphosph(III)azanes i-PrN[PhP(i-PrNH)](PhPR) (R = Me, Et, Ph, t-Bu) form diastemselectively in reactions of RNH2 with i-PrN[PhP(i-PrNH)](PhPCl). Reactions of 1,3,2-diazaphospholes C6H4(NH)2PR with RPCl2 and RP(Net2)2 (R = Me, Ph) yield i-PrN[PhP(i-RNH)][PhP(RNH)] and C6H4(NH)PRNP(R)X(X=Cl, NEt2), respectively, with modest stereoselection. New diazaphosph (III) azanes are characterized by spectral (31P, 1H, 13C NMR, IR, MS) data and single crystal x-ray analyses of i-PrN[PhP(i-PrNH)][PhP(EtNH)] and C6H4(NH)PEtS(N)P(NEt2)EtS are described.
