Abstract
[CO(CO)2(R2PCH2)3CCH2PR2][CO(CO)4] (R = C6H5) was synthesized in a simple manner from Co2(CO)8 and the tetratertiary phosphine C[CH2P(C6H5)2]4, which acts only as a tridentate ligand. [Co(CO)2(R2PCH2)3CCH2PR2][Co(CO)4] reacts with NH4PF6, NaBH4, NaBD4 or liquid ammonia at 20 °C to [Co(CO)2(R2PCH2)3CCH2PR2]PF6, CoH(CO)2(R2PCH2)2C(CH2PR2 · BH3)2, CoD(CO)2(R2PCH2)2C(CH2PR2 · BD3)2 or Co(CO)(CONH2)(R2PCH2)3CCH2PR2. In liquid ammonia [Co(CO)2(R2PCH2)3CCH2PR2][Co(CO)4] at 60 °C yields the hydride CoH(CO)(R2PCH2)3CCH2PR2. The new compounds were characterized, as much as possible, by their IR, Raman and 1H NMR data.Keywords
