The reaction of benzyl or 1-phenylethyl 2-pyridyl sulfoxide with Grignard reagent proceeds via a ?-sulfurane as an intermediate to give the coupling product, 2-benzylpyridine or 2-(1-phenylethyl)pyridine in quantitative yield.Stereochemistry for this reaction is complete retention at the benzylic carbon atom.

The reaction of benzyl or 1-phenylethyl 2-pyridyl sulphoxide (1) or (18) with a Grignard reagent was found to give the ligand-coupling product, i.e., 2-benzylpyridine or 2-(1-phenylethyl)pyridine (2) or (22) in excellent yield.This coupling reaction was found to proceed whithin the ?-sulphurane formed as an intermediate upon treatment of benzyl 2-pyridyl and related sulphoxides with a Grignard reagent.The stereochemical course of this coupling reaction involves complete retention at the benzylic carbon.
