摘要：

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 in the blue. Both undergo irreversible one electron oxidation at similar to1.1 mV versus Ag/Ag+ electrode, consistent with oxidation of the benzo[b]thiophene nuclei rather than the substituent thiophene rings.
