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 eithero-phenylenediamine and 3,4-diaminobenzoic acid or with benzaldehyde andp-nitrobenzaldehyde in the presence of ammonium acetate.
通过使用苯乙炔和 4,4'-二溴苄基之间的交叉偶联的改进方法,然后将获得的 4,4'-二(苯基乙炔基)苄缩合,以高产率合成双 [p-(苯乙炔基)苯基]亚杂芳基化合物。 -苯二胺和3,4-二氨基苯甲酸或在乙酸铵存在下与苯甲醛和对硝基苯甲醛。
