Photochemical transformations. Part XXXII. Photolysis of thiobenzoic acid O-esters. Part III. Photolysis of O-phenethyl thiobenzoates and other thiobenzoates
Abstract
Homoallylic alcohols can be dehydrated under exceptionally mild conditions by conversion into their thiobenzoate O-esters and irradiation between –70° and room temperature. A variety of substrates have been dehydrated by this method.
