Photolysis and Thermolysis of some substituted 2,5 - dihhydrothiophenes

By Willem Lodewijk Prins


∆3-1,3,4-thiadiazolines were found by Kellogg and coworkers to eliminate thermally nitrogen to give a thiocarbonyl ylide. Some aspects of the thermal reaction could be related to the theory of Woodward and Hoffmann. It was of interest to investigate the photochemical behaviour of ∆3-1,3,4-thiadiazolines. Several photochemically induced concerted electronic reorganization possibilities are open both on the basis of orbital symmetry conservation and also from literature precedent (CH.I) ...
