The homolytic heterocyclization of dialkyl-, and diaryl-acetylenes with 1,2-ethanedithiol leads stereoselectively to cis-2,3-disubstituted 1,4-dithianes.The stereochemistry of the reactions is determined by a combination of homolytic trans addition at the triple bond and intramolecular homolytic cis addition at the double bond.The main product of the heterocyclization of dimethyl acetylenedicarboxylate is dimethyl 5,6-dihydro-1,4-dithiin-2,3-dicarboxylate.
