, p. 904 - 914 (2007/10/03)
Studies on the synthesis of various 2-styrylbenzimidazoles 3, 7 and N-methylated 2-styrylbenzimidazoles 5, 9 from 2-methyl/ethyl benzimidazoles 2, 6 and 1,2-dimethyl/1-methyl-2-ethylbenzimidazoles 4, 8 respectively by condensation with different aromatic aldehydes are described. The spectral characteristics of 2-styrylbenzimidazoles and N-methylated-2-styrylbenzimidazoles are discussed. An efficient and convenient phase-transfer catalysed methylation procedure for the synthesis of N-methylated-2-styrylbenzimidazoles from 2-styrylbenzimidazoles is reported.
