Improved synthesis of bis[p-(phenylethynyl)phenyl]hetarylenes

Bis[p-(phenylethynyl)phenyl]hetarylenes were synthesized in high yields by an improved method using cross-coupling between phenylacetylene and 4,4′-dibromobenzil followed by condensation of the 4,4′-di(phenylethynyl)benzil obtained with either o-phenylene

Synthesis of new bis[p-(phenylethynyl)phenyl]hetarylenes and bis[p-(phenylglyoxalyl)phenyl]hetarylenes

A series of new bis[p-(phenylethynyl)phenyl]hetarylenes was obtained by cross-coupling between heteroaromatic dibromides and phenylacetylene catalyzed by phosphine complexes of palladium in the presence of Cul and an organic base. Bis[p-(phenylethynyl)phe
