Synthesis, spectral characteristics and electrochemistry of symmetrically-substituted hybrids derived from 2,5-bis(4- bromophenyl)-1,3,4-oxadiazole under Suzuki cross-coupling reaction
2015
New symmetrically substituted derivatives of 2,5-bis(4-arylphenyl)-1,3,4-oxadiazole were prepared from 2,5-bis(4-bromophenyl)-1,3,4-oxadiazole and various thiophene-, furan-, pyridine- or benzene-containing boronic acids by a palladium catalyzed Suzuki cross-coupling reaction under the conditions of the phase transfer catalysis. The structure of the products, the absorption and emission spectra and their electrochemistry were also studied.
