Abstract
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.File in questo prodotto:
