Facile synthesis, structural elucidation and spectral analysis of pyrrole 4-imidazole derivatives
In this work pyrrole 4-imidazole derivatives (3A-3D): benzimidazoles and pyrrole 4-imidazoline have been synthesized by condensation, cyclization and oxidation of ethyl 4-formyl-3,5-dimethyl-1H-pyrrole carboxylate and phenylene diamine derivatives/ethylene diamine. The structure of these biheterocyclic compounds have been derived by elemental and spectroscopic – IR, UV, MS, H-1 and C-13 NMR analysis as well as theoretical study. The static first hyperpolarizability, beta(0) values for pyrrole 4-imidazole derivatives, (3A-3D) have been calculated as 10.901 x 10(-31), 19.607 x 10(-31), 40.323 x 10(-31), 5.686 x 10(-31) esu, respectively. The gradual increase in beta(0) value of synthesized pyrrole-benzimidazole derivatives from 3A to 3C is due to addition of acceptors -Cl atom in 3B to -NO2 group in 3C on benzimidazole side. The experimental absorption spectra found to be in UV region and the high beta(0) values show that the synthesized pyrrole-imidazoles are suitable as non-linear optical (NLO) materials.
