The suggestion has been made' that the most stahle form of protonated phosphinamides has the proton on nitrogen rather than on the phosphoryl oxygen. Among other evidence, the coupling constant, J PNCH, was observed to decrease upon protonation of two different phosphinamides, lb -\_

Theoretical calculations at the 3-21G and 3-21+G ab initzo levels and at the MNDO and AM1 semiempirical levels of several six-membered nitrogenated heterocycles and their protonated species have been carried out. The 3-21G calculated proton affinities are systematically too high, in relation to the
