Abstract


Sonogashira reactions of 4-(2,5-diiodobenzoyl)morpholine and 4-(5-bromo-2-iodobenzoyl)morpholine with arylacetylenes catalyzed by Pd2(dba)3 in DMSO allowed preparation of fluorescent oligo(p-phenyleneethynylene)s (OPE3) with fluorescence quantum yields up to 0.87. DMSO proved to be very efficient for this double Sonogashira coupling in which other solvents failed.
