✦ Synopsis

The measurement of rotational barriers for P(III)-N bonds by n.m.r. methods is now commonplace, 1 but such barriers involving P(V)-N bonds at four co-ordinated phosphorus are not generally accessible by this technique 2 and none has been reported for a dimethylamino-group.

Even with relatively bulky di(isopropyl) amino-groups in RP(S)CINPri21 and in dithia-
