The mechanism of the formation of 4,5,9,10-tetrahydrocyclocta[1,2-c; 5,8-c′]dithiophene from bis(2-chloropropen-3-yl)sulfide has been studied by quantum chemistry methods, UV, and IR spectroscopy. Possible routes of the polycyclic structures generation in the medium of 3,4-dimethylentiophene diradicals during the synthesis of 4,5,9,10-tetrahydrocycloocta[1,2-c; 5,8-c′]dithiophene are analyzed at DFT
