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