Popis:	Reductive cyclization by McMurry method was performed with diketosulfide obtained by treating with Na2S of compound prepared by regioselective acylation of methyl 2-methyl-4H-thieno[3,2-b]pyrrole-5-carboxylate with chloroacetyl chloride. As a result was synthesized a photochromic 1,2-dihetarylethene where the fuzed rings are connected by a 2,5-dihydrothiophene ring. The oxidation of the latter provides 2,5-dihydrothiophene-1,1-dioxide bridge.
