H20, MeOH, PhNH2, Et2NH) to give the corresponding [RP (H) A] M (CO) 6 secondary phosphine complexes (R= Ph, Me) through cleavage of thephosphorus bridge of the phos-phanorbornadiene skeleton. The phosphorus-hydrogen bond of these compounds is veryresistant toward oxidation. In one case, it has been successfully metalated by t-BuOK inTHE and, then, either alkylated by methyl iodide or condensed with benzophenone. The phosphorus-nitrogen bond of [PhP (H)-(NHPh)] W (CO) s is easily cleaved at room temperature by hydrogen halides to give the first known stable secondary halophosphine complexes [PhP (H) X] W (CO) 6 (X= Cl, Br, I). The chloro compound reacts with ammonia and NaSH at room temperature to give, respectively,[PhP (H) NH2] W (CO) 5 and S [PhPH—W-(CO) 6] 2. In the presence of aluminum trichloride, the dismutation of thechloro compound yields equal amounts of [PhPH2] W (CO) 6 and [PhPCl2] W (CO) 5. All these compounds are stable and have been completely characterized by 1H NMR, 31P NMR, IR, and mass spectrometry and elemental analyses.
