Treatment of a series of 4-phenylsulfanyl-1,3-diols with toluene-p-sulfonyl chloride in pyridine gives stereospecifically substituted allylicalcohols in near quantitative yield via a [1,4]-SPh shift. We comment on the structural variation at both the migration origin and terminus on the outcome of the title reaction and define its limits.

Rearrangement of 4-PhS-1,3-diols with TsCl in pyridine gives allylicalcohols. We discuss the scope and limitation of this reaction using structural variations, which help to elucidate the mechanism of the reaction. All reactions proceed in high yield and give synthetically useful products.
