Abstract

[Pt-3(mu-CO)(3)(PPh3)(3)] was prepared in high yield by the reaction of [Pt-3(mu-CO)(3)(PPh3)(4)] with H2O2. The carbonyl ligands in [Pt-3(mu-CO)(3)(PR3)(3)] (PR3 = PPh3, PPh(2)Bz, PCy3, P'Pr-3) may be completely replaced by sulfur dioxide to give [Pt-3(mu-SO2)(3)(PR3)(3)] or partially by one SO2 to give [Pt-3(mu-CO)(2)(mu-SO2)(PR3)(3)] (PR3 = PCy3 and (PPr3)-Pr-i). On the other hand, the addition of one molar equivalent of carbon monoxide to [Pt-3(mu-SO2)(3)(PR3)(3)] (PR3 = PCy3, (PPr3)-Pr-i) gave the complexes [Pt-3(mu-CO)(mu-SO2)(2)(PR3)(3)] Complete simulation of the C-13 NMR spectra could be achieved with the help of Pt-195 NMR data.

Metal carbonyl

Metal carbonyls are coordination complexes of transition metals with carbon monoxide ligands. Metal carbonyls are useful in organic synthesis and as catalysts or catalyst precursors in homogeneous catalysis, such as hydroformylation and Reppe chemistry. In the Mond process, nickel tetracarbonyl is used to produce pure nickel. In organometallic chemistry, metal carbonyls serve as precursors for the preparation of other organometallic complexes.

Metal carbon dioxide complex

Metal carbon dioxide complexes are coordination complexes that contain carbon dioxide ligands. Aside from the fundamental interest in the coordination chemistry of simple molecules, studies in this field are motivated by the possibility that transition metals might catalyze useful transformations of CO2. This research is relevant both to organic synthesis and to the production of "solar fuels" that would avoid the use of petroleum-based fuels. Carbon dioxide binds to metals in only a few ways.

Carbonyl group

In organic chemistry, a carbonyl group is a functional group with the formula , composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acids), as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carbonyl compound. The term carbonyl can also refer to carbon monoxide as a ligand in an inorganic or organometallic complex (a metal carbonyl, e.
