Directed dilithiation of hexafluorocumyl alcohol - formation of a reagent for the facile introduction of a stabilizing bidentate ligand in compounds of hypervalent sulfur (10-S-4), phosphorus (10-P-5), silicon (10-Si-5), and iodine (10-I-3)
Diaryl sulfoxidesbearing 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.
