    Description / Table of Contents: Transition Metal Sulfur Ylide Complexes, XV. Synthesis of 2H-Thiopyran Chromium Complexes from Tetraethylammonium Tricarbonyl- (η-3,5-diphenyl-1-thiacyclohexadienyl 1-oxide)chromate and Hard ElectrophilesThe reactions of tetraethylammonium tricarbonyl(η5-3,5-diphenyl-1-thiacyclohexadienyl 1-oxide)chromate (2a) with methyl fluorosulfonate and N-sulfinyldimethylimmonium tetrafluoroborate, respectively, yield the 2H-thiopyran complexes 4 and 9 instead of the expected λ4-thiabenzene complexes 3 and 8. The molecular structure of 9 was elucidated by X-ray analysis.
    Notes: Bei der Reaktion von Tetraethylammonium-tricarbonyl(η5-3,5-diphenyl-1- thiacyclohexadienyl-1-oxid)chromat (2a) mit Fluorsulfonsäure-methylester bzw. N-Sulfinyldimethylimmonium-tetra-fluoroborat werden statt der erwarteten λ4-Thiabenzolkomplexe 3 und 8 die dazu isomeren 2H-Thiopyrankomplexe 4 und 9 isoliert. Die Molekülstruktur von 9 wurde durch Röntgenstrukturanalyse aufgeklärt.
