Abstract

The organometallic anion in tetraethylammonium-tricarbonyl(3,5-diphenylthiacyclohexadienyl-1-oxide )molybdate and its tungsten analogue can be halogenated by treatment with iodine, C5H5N·Br2, and I,I-dichloroiodobenzene to yield neutral [η5-C5H3(C6H5)2SO]M(CO)3X complexes (M=Mo, W; X=Cl, Br, I).
