Übergangsmetall-Schwefelylid-Komplexe, XXII [1] Zur Reaktivität von DicarbonylnitrosyI-η5-thiacyclohexadienyl-1-oxid- Chromkomplexen gegenüber Phosphor- und Schwefelyliden / Transition Metal Sulfur Ylide Complexes, XXII [1] Reactivity Studies of Dicarbonylnitrosyl-η5-thiacyclohexadienyl-1-oxide Chromium Complexes with Phosphorus and Sulfur Ylides

3a-dη5-Thiacyclohexadienyl-1-oxide chromium complexes are generated by treatment of the 1-methyl-thiabenzene-1-oxide complexes 1a-d with Li[BHEt3] and successive nitrosylation of the intermediates 2a-d. 3a-d react with Me2S(O) = CH2 or Ph3P=CH2 at a carbonyl ligand in an additon/transylidation process to yield the very sensitive products 5, 6a-d.
