Reaction Steps
α-Terthienyl (2.46 g, 0.01 m) was treated with two equivalents of chlorosulfonyl isocyanate (0.02 m) in methylene chloride as described in the preparation of 5-cyano-2,2':5',2"-terthienyl. Work-up as in that procedure gave crude product (2.4 g), m.p. 165°-170° C., contracting around 140° C. m/z 298(m+);
