New anionic carbonylcobalt(I) complexes (X2Co(CO)2(PPh3))(PR4) (X=Cl, PR4=PBzPh3 (I); X=Br, PR4=PEtPh3 (II)) have been prepared by reduction of the cobalt(II) halides with NaBH4 in the presence of PPh3 and the phosphonium salt PR4X.Cleavage of halide bridges in dimeric or polymeric (XCo(PPh3)2)n and (XCo(PPh3))n gives the neutral dicarbonyl derivatives XCo(CO)2(PPh3)2.Treatment of ClCo(CO)2(PPh3)2 with alkylating agents gives the known ?- and η-organocobalt(I) derivatives, and reactions with TlClO4 in the presence of various amounts of different mono- and bi-dentate phosphines give the cationic tricarbonyl (Co(CO)3(PPh3)2)(+), dicarbonyl (Co(CO)2(PMePh2)3)(+) and monocarbonyl (Co(CO)L4)(+) complexes (L4=4P(OMe)3, 2 dppe and 2 dppm).The dppm complex crystallizes in the monoclinic space group P21/c with a 17.895(6), b 10.751(2), c 24.687(4) angstroem, β 98.92(1) deg, and Dcalc 1.35 g cm-3 for Z=4.A final R value of 0.077 (Rw=0.061), based on 2656 observed reflections, was obtained.The cobalt atom exhibits a distored trigonal bipyramidal geometry.The perchlorate anion is severely disordered or freely rotating.

The dithiocarbene complex Cp(CO)(MeCN)Fe=C(SMe)2+ reacts with Fe(CO)3(NO)- to give the dinuclear complex Cp-(CO)Fe(μ-CO)[μ-C(SMe)2]Fe(CO)(NO) in which the C(SMe)2 ligand bridges the two met
Reversible addition of carbon monoxide to tertiary phosphine complexes of cobalt(II) and their reduction to cobalt(I) carbonyl derivatives

, p. 1733 - 1737 (2007/10/05)
The reactions of carbon monoxide with complexes of the type Co(PR3)2X2 (PR3 = tertiary phosphine, X = mononegative ion) have been studied in C2H4Cl2 and benzene. The reaction und
