    Description / Table of Contents: Transition Metal Sulfur Ylide Complexes, IX1) π-Complexes of 1-Alkyl-3,5-diphenylthiabenzene 1-Oxides with Dicarbonylnitrosylchromium, -molybdenum, and -tungsten1-Alkyl-3,5-diphenylthiabenzene 1-oxide chromium complexes 2a-f1) are oxidized by NOPF6 in CH2Cl2 at -70°C, yielding the cationic dicarbonylnitrosyl complexes 3a-f. Stable analogous complexes of molybdenum and tungsten can be isolated if the sulfur atom of the ring is substituted by electron releasing and bulky groups such as CH(CH2Ph)2 or CH(SiMe3)2.
    Notes: Die 1-Alkyl-3,5-diphenylthiabenzol-1-oxid-Chromkomplexe 2a-f1) werden durch NOPF6 in CH2Cl2 bei -70°C unter Bildung der kationischen Dicarbonylnitrosyl-Spezies 3a-f oxidiert. Die Isolierung analoger stabiler Komplexe von Molybdän und Wolfram gelingt, wenn sich am Schwefel stark elektronenspendende und sperrige Substituenten wie CH(CH2Ph)2 oder CH(SiMe3)2 befinden.
