Reaction of dichloro- and diiodo-(1,5-cyclooctadiene)platinum(II) with excess diazomethane affords the corresponding air-stable bis(halomethyl) complexes Pt(CH2X)2(COD) (X=Cl or I) in excellent yield.Displacement of COD from Pt(CH2Cl)2(COD) with 1,3-bis(diphenylphosphino)propane or two molar equivalents of PPh3 gives the analogous phosphine complexes.
