 Title    Darstellung und Struktur kationischer i^-Thiocarbenkomplexe von Molybdän und Wolfram Synthesis and Structure of Cationic //2-Thiocarbene Complexes of Molybdenum and Tungsten  
 Abstract    The reaction o f dim ethyl(m ethylthio)sulfonium tetrafluoroborate [(CH-,)-,S-SCH3][BF4] with //;'-cyclopentadienyl(dicarbonyl)carbyne com plexes o f molybdenum and tungsten Cp(CO)2M = C -R (M = M o. W; R = C H ,, C6H 5, C6H4C H 3) lc , 2 a ~ d results in an electrophilic attack o f the SCH, moiety at the metal carbon triple bond, providing orange to red, diam ag­ netic, cationic //--thiocarbene com plexes [Cp(CO):M = C(R)$CH,J[BF4] 3c, 4 a ~ d in high yields. The new com pounds were identified by X-ray structure analysis, N M R , IR and mass spectra.
