Contrary to general belief, it is shown that complete aminolysis of tetrameric phosphonitrilic chloride can be effected with a variety of amines. It is shown, further, that by use of the proper ratio of reactants tetrasubstituted derivatives can be obtained also. If the amine is sufficiently sterically hindered, only the tetrasubstituted derivative can be obtained. iYuclear magnetic resonance data suggest that in such tetrasubstituted materials each phosphorus ...
