Abstract
Studies on the synthesis of various 2-styrylbenzimidazoles 3, 7 and N-methy lated 2-styrylbenzimidazoles 5, 9 from 2-methyl/ethyl benzimidazoles 2, 6 a nd 1,2-dimethy/1-methyl-2-ethylbenzimidazoles 4, 8 respectively by condensa tion with different aromatic aldehydes are described. The spectral characte ristics of 2-styrylbenzimidazoles and N-methylated-2-styrylbenzimidazoles a re discussed. An efficient and convenient phase-transfer catalysed methylat ion procedure for the synthesis of N-methylated-2-styrylbenzimidazoles from 2-styrylbenzimidazoles is reported.
