Title full: Some reactions of the platinum(II) carbene complex cis-dichloro(dimethylaminomethylene)(triphenylphosphine)-platinum(II) and the X-ray crystal and molecular structures of the products trans-(CH 2,P)-chloro(chloromethyl)(dimethylaminomethylene)(triphenylphosphine) platinum(II) and [1,2-bis(diphenylphosphino)ethane](dimethylaminomethylene)-(triphenylphosphine) platinum(II) bis(hexafluorophosphate). The reaction of the title complex 1 with excess diazomethane results in the exclusive insertion of a methylene group into the Pt-Cl bond trans to the phosphine ligand, to give the chloromethyl complex 6. The reactions of 1 with the diphosphines, Ph2P(CH2)nPPh2(n = 2, dppe, n = 3, dppp), and with the organometallic reagents Ph4Sn, Ph2Hg, or PhSnMe3, can also all be interpreted as proceeding via initial displacement of the chlorine trans to PPh3. The chelating phosphine ligands give equilibrium mixtures of the products [(LL)Pt(CHNMe2)(PPh3)]2+2Cl- and [(LL)Pt(CHNMe2)Cl]+Cl- (LL = dppe, dppp), and treatment of the mixture [(LL) = dppe] with excess aqueous KPF6 gave [(dppe)Pt(CHNMe2)(PPh3)]2+2PF6 - (9b).
