Abstract
A reinvestigation of the reaction of the dihydrothiophenes (1a,b) with thionyl chloride confirmed that the sulphines (2) are the products obtained, the structure of (2a) being ascertained by X-ray diffraction analysis of its Diels–Alder adduct (3a): the same reaction on dihydrothiophene (6) produced the corresponding sulphine (7)Keywords
