In this paper, we first report a new class of halide-free and bifunctional one-component catalysts for the coupling of CO2 with epoxides. The catalysts do not need halide-based additives or tethered salts attached to the ligand when used for this coupling reaction. As the halide-free and bifunctional one-component catalysts, we chose nonionic and monomeric tetracarbonylchromium(0), tetracarbonylmolybdenum(0)

Die Reaktion von [Me2GaHNC(Me)}2CCN] (1) mit fac-[Mo(CO)3(MeCN)3] fuhrt nach Umkristallisieren aus TMEDA zum Mo-Komplex fac-[Mo(CO)3(1) (TMEDA)] (2). Unter identischen Reaktionsbedingungen kann mit fac-[W(CO)3(MeCN)3] nur der Tetracarbonyl-Komplex [W(CO)4(TMEDA)] (3) isoliert werden。Umsetzungen des dilithierten 1 mit Me2SiCl2 bzw。InCl3 Losen eine Spaltung des Gerustes von 1 aus。Gewonnen 和 charakterisiert

The potentially bidentate antimony ligand (C6H5)2SbCH2Sb(C6H5)2 (Dpsm) has been allowed to react with the Group VIB metalcarbonyls and some of their derivatives under a variety of synthetic conditions. Molecular structures and bonding behavior of the substituted complexes M(CO)5(Dpsm), M(CO)4(Dpsm), [M(CO)4(Dpsm)]2, and Mo(CO)3(Dpsm)2 are based upon NMR and infrared spectral studies and molecular
