Trifluorophosphine halides

Other routes involve treatment of a metal-trifluorophosphine halide with either sodium or lithium cyclopentadienide (method D), or direct reaction between a metal-PF3 complex and cyclopentadiene (method E). 

The reductive fluorophosphination of metal halides in the presence of copper and hydrogen gas at high temperature and pressure offers a useful synthetic route for a number of hydrido trifluorophosphine metal complexes (method A). 

Oxidative addition of an allyl halide to a zero-valent complex (method D) or treatment of a trifluorophosphine metal late complex with an allylic halide followed by loss of PF3 (method E) have also been briefly reported. 

Reductive fluorophosphination of metal halides in the presence of hydrogen will lead to some very stable complexes which contain covalently bound hydrogen (8.187) and (8.188). The proton can be removed from trifluorophosphine metal hydrides by weak bases, to form ionic trifluorophosphine metallates such as K Ir(PF3) . ...
