Trimethylsilyldiazomethane as a diazomethane equivalent in the synthesis of (α-halomethyl) platinum(II) complexes
摘要:
The reaction between [PtX(2)L(2)] (X = Cl, Br, I; L(2) = 1,5-cyclo-octadiene (cod), 2PPh(3), 2PMePh(2), Ph(2)PCH(2)CH(2)PPh(2), S,S-Ph(2)PCHMeCH(2)CHMePPh(2) (S,S-skewphos)) and an excess of Me(3)SiCHN(2) in a CH2Cl2/Me(2)CO/H2O solvent mixture gives the complexes [Pt(CH(2)X)(2)L(2)]. When [PtX(2)(cod)] is treated with Me(3)SiCHN(2) in a CH2Cl2/Me(2)CO/D2O solvent mixture, the complexes [Pt(CHDX)(2)(cod)] are formed exclusively. The mechanism of these reactions is discussed.
