1, 4-Dithiine and its derivatives have not been well studied [1]. We synthesized 2, 6-diphenyl- 1, 4-dithiine for the first time [2] by hydrothiolysis of diphenacyl sulfide at-20 C. The reaction occurs through a step of formation of thiophenacyl (2-mercapto-2-phenylvinyl) sulfide [3]. Continuing a study of the chemical properties of α-halo-gem-dithiols [4], we observed that the reaction of an ether solution of 1-phenyl-2-chloroethane-1, 1-dithiol (1) with an ...
