  名称：

  E/Z isomerism in monoalkylated derivatives of [Pt₂(µ-S)₂(PPh₃)₄] containing 2,4-dinitrophenylhydrazone substituents

  摘要：

  Alkylation of [Pt-2(mu-S)(2)(PPh3)(4)] with 2,4-dinitrophenylhydrazone-functionalized alkylating agents XC6H4C{=NNHC6H3(NO2)(2)} CH2Br (X = H, Ph) gives monoalkylated cations [Pt-2(mu-S){mu-SCH2C{=NNHC6H3(NO2)(2)}C6H4X}(PPh3)(4)](+). An X-ray diffraction study on [Pt-2(mu-S){mu-SCH2C{=NNHC6H3(NO2)(2)}Ph}(PPh3)(4)]BPh4 shows the crystal to be the Z isomer, with the phenyl ring and NHC6H3(NO2)(2) groups mutually trans. H-1- and P-31{H-1} NMR spectroscopic methods indicate a mixture of Z (major) and E (minor) isomers in solution, which slowly convert mainly to the E isomer. Reaction of [Pt-2(mu-S)(2)(PPh3)(4)] with the dinitrophenylhydrazone of chloroacetone [ClCH2C{=NNH(C6H3(NO2)(2)}Me] and NaBPh4 gives [Pt-2(mu-S){mu-SCH2C{=NNHC6H3(NO2)(2)}Me}(PPh3)(4)]BPh4, which exists as a single (E) isomer.
