The chemistry of cyclometalated organometallic compounds is of great current interest, on the basis of applications of such compounds in stoichiometric or catalytic organic synthesis and in sensing and functional materials . As in other areas of organometallic chemistry, studies of the cyclometalation of platinum complexes have given many interesting complexes as well as new insight into the mechanisms of the reactions. 2-Phenypyridine (abbreviated as HC^N) and biphosphines (PP) are two of the most common and important classes of ligands employed in organometallic chemistry. The cyclometalated organoplatinum(II) complexes with chelating bis (diphenylphosphino) ethane [Pt (κ1-C-C^N) R (dppe)], 2, in which C^N is ppy ( deprotonated 2-phenylpyridine) were reacted with dimethylplatinum complex [Pt Me2 (dmso)2], 3, to give [Pt (C^N) R (dmso)], 1’, and [Pt Me2 (dppe)], 4. The reaction was studied by multinuclear NMR spectroscopy and the reaction pathway and mechanism of this dppe migration was proposed and confirmed by DFT calculations.
