Aminophosphines RP(NR′2)2 (R Ph, cyclo-Hex, (−)-Men, t-Bu; R′ Me, Et) as ligands L in complexes (CO)5ML (M Cr, Mo, W) have been found to react with HX (X Cl, Br) mainly under substitution of only one of the two dialkylamino groups by halogen. Under similar conditions the free phosphines are converted into the dihalogenphosphines. The halogenamino complexes (CO)5MPRXNR′2 are readily accessible

A new compound tertiarybutylbis-(dimethylamino)phosphine and a process for preparing the compound, which has the formula ((CH.sub.3).sub.3 C) ((CH.sub.3).sub.2 N).sub.2 P. The process has the steps of: (1) reacting phosphorus trihalide, PX.sub.3, with tertiarybutyl Grignard reagent, ((CH.sub.3).sub.3 C)MgX, where X is a halide; (2) treating the resulting product with lithium dimethylamide, LiN(CH.sub.3).sub.2 to form a reaction mixture; and (3) recovering ((CH.sub.3).sub.3 C) ((CH.sub.3).sub.2 N).sub.2 P from the reaction mixture.
