Abstrakt: The substituted metallocene compounds Cp2M(OSO2CF3)2 (Cp=η5-C5H5; M = Ti, Zr, Hf, Nb, Mo), CpTi(OSO2CF3)3 · 0.75(1,2-dimethoxyethane), and the organo-main group compounds (C6H5)3M′(OSO2CF3) (M′=Si, Ge), (C6H5)2Sn(OSO2CF3)2 and (C6H5)3Sb(OSO2CF3)2, were synthesized from the corresponding chloride or bromide compounds and silver trifluoromethanesulfonate (triflate) and characterized spectroscopically, including a detailed analysis of their IR spectra. Triflate coordination is typically monodentate, but CpTi(OSO2CF3)3 · 0.75(1,2-dimethoxyethane) and the organo-germanium triflate show evidence of bidentate CF3SO [ABSTRACT FROM AUTHOR]
