Abstract An improved preparation of the P(III) fluorohalides, XPF2 (X = C1, Br) and of C12PF from the scrambling reaction of Et2NPF2 with PX3 (X = C1, Br) and of (Et2N)2PF with PC13, respectively, is described. An alternate synthesis of CIPF2 is based on a modification of the previously known P-N cleavage reaction of R2NPF2 with HC1. Characterization of the halophosphorus(III) fluorides, all previously known, was by 19F and 31P n.m.r. spectroscopy.
