Reactions of Sulfoxides Bearing ortho-Sulfur Functional Groups and Thianthrene Monoxide with Grignard Reagents

Article abstract of DOI:10.1246/cl.1990.979

Diaryl sulfoxides bearing ortho-sulfur substituents react readily with Grignard reagents on the sulfur atom to produce the corresponding phenyl Grignard reagents bearing ortho-sulfur functional group.Furthermore, thianthrene monooxide was found to react with alkyl Grignard reagents affording o,o'-bis-Grignard reagent of diphenyl sulfide which was converted easily to Martin's sulfurane.
