Abstract
2,6-Dimethoxyphenyldifluorophosphine, 1, when allowed to stand for several days in solution in CDCI3, was found to undergo a spontaneous transformation to the tetrafluorophosphorane, ArPF4, 2, and to the unusual 1,2-dichlorodiphosphine, ArP(Cl)P(Cl)Ar, 3, (Ar = 2,6-dimethoxyphenyl). Compounds 2 and 3 were characterized by n.m.r. spectroscopy and, in part, by elemental analysis. A possible pathway, rationalizing the formation of 2 and 3 is indicated. An X-ray crystal structure determination of 3 has been conducted. The molecule was found to display a staggered conformation, with a PP bond length of 223.6 pm.Keywords
