Carboxylation of pincer PCP platinum methoxide complexes under formation of metalla carbonates

Summary, in English

The ligand 2,6-bis[(diphenylphosphino)methyl]benzene ((PCP)H) was prepared and characterised in an improved manner. With platinum it forms the complex (PCP)PtOTf which reacts with sodium methoxide to give (PCP)PtOMe as the major product together with a small amount of [(PCP)Pt](2)-mu-H. The platinum methoxide reacts with carbon dioxide to give (PCP)PtO(CO)OMe. Also the dinuclear [(PCP)Pt](2)(mu-O(CO)OMe) is formed in this reaction if (PCP)PtOTf is present. The crystal structures for [(PCP)PtOH2]OTf, PCP)PtOMe, [(PCP)Pt](2)-mu-H and [(PCP)Pt](2)(mu-O(CO)OMe) are reported. (c) 2011 Elsevier Ltd. All rights reserved.
