The title compound, C 16 H 6 Br 2 Cl 2 N 2 S 2 , was synthesized from the reaction of equimolar amounts of 1,2-diamino-4,5dichlorobenzene and 1,2-bis(5-bromothien-2yl)ethanedione. The crystal structure was determined at 100 K.
## Abstract Activated dihydridocarbonyltris(triphenylphosphine)ruthenium catalyzes the cyclodimerization of both bis(2‐thienyl)acetylene and bis(3‐thienyl)acetylene to yield, respectively, 4,5,6‐tris(2′‐thienyl)‐benzo[__b__]thiophene and 5,6,7‐tris(3′‐thienyl)benzo[__b__]thiophene. These fluoresce
