Trifluorophosphine

Since fluorophosphines form part of a general review of phosphorus fluorides (282), and there is an excellent account of transition metal-trifluorophosphine complexes (152), the present article is not intended to be comprehensive, but rather to highlight some of the more recent developments in this expanding area of inorganic chemistry. 

The parent compound trifluorophosphine (b.p. — 101.4°C) will only be discussed briefly since preparative methods, physical properties, and general reactions have been adequately discussed previously by Schmutzler (282) and will not be repeated here. Usually trifluorophos- 

The molecular structure of trifluorophosphine has been the subject of several papers and considerable differences in bond length and bond angles have been reported. The very early work by Brockway et al. 33, 258) gave r(P-F) = 1.52 A, 0(FPF) = 104°, and more recently Hersh (13i) found r(P-F) = 1.537 0.04 A, 0(FPF) = 98.2° 0.6°. In neither case, however, were these data consistent with microwave studies [113, 208, 209). 

In a very recent electron diffraction study (211) r(P-F) is found to be 1.570 A and 0(FPF) = 97.8° and these results are in accord with the microwave data.  

There is disagreement about the importance of d-orbital participation in trifluorophosphine. On the basis of dipole moment data and using a
