Thirty-four @2-R1C2R2)Co2(C0)6 complexes (14 new) were prepared and characterized by their IR v(C0) and lH- and 13C-NMR spectra. The 13C-NMR chemical shifts of the coordinated sp carbon atoms were correlated with those of the corresponding free acety

We report here the first systematic investigation of the effects of concentration and properties of tertiary phosphines on the chemoselectivity of the homogeneous catalytic hydrosilylation of phenylacetylene with triphenylsilane using Nickel(O) catal

An [(alkoxycarbonyl)methyl]cobalt tetracarbonyl ( 1 ) derivative (alkyl = Et, 1a ) was treated with tertiary phosphorus ligands. A monosubstituted acyl derivative EtOC(O)CH 2 C(O)Co(CO) 3 L ( 2 ), L = PPh 3 ( 2f ) was isolated, and other new complexe

Mono- and disubstitution of HCo(CO)4 with tertiary phosphines and phosphites was studied by IR and1H-NMR spectroscopy. It was found that these substitutions proceed through phosphonium tetracarbonylcobaltate intermediates, leading to a mixture of iso
