The reaction between [PtX₂L₂] (X = Cl, Br, I; L₂ = 1,5-cyclo-octadiene (cod), 2PPh₃, 2PMePh₂, Ph₂PCH₂CH₂PPh₂, S,S-Ph₂PCHMeCH₂CHMePPh₂ (S,S-skewphos)) and an excess of Me₃SiCHN₂ in a CH₂Cl₂/Me₂CO/H₂O solvent mixture gives the complexes [Pt(CH₂X) ₂L₂]. When [PtX₂(cod)] is treated with Me₃SiCHN₂ in a CH₂Cl₂/Me₂CO/D₂O solvent mixture, the complexes [Pt(CHDX) ₂(cod)] are formed exclusively. The mechanism of these reactions is discussed.
