TI Investigation on the Reaction Mechanism for the Synthesis of Benzimidazole Derivatives from Aldehydes and o-Phenylenediamine
SO CHINESE JOURNAL OF ORGANIC CHEMISTRY
AB The synthesis of 2-(4-methyphenyl)benzimidazole from 4-methyl benzylaldehyde and o-phenylenediamine was performed. The reaction process was monitored by HPLC, and the structures of related intermediates and products were identified by (1)H NMR, FT-IR and LC-MS techniques. The experiments proved that mono-Schiff base and bis-Schiff base could both be synthesized at the same time when o-phenylenediamine and aldehydes were in a molar ratio of 1 : 1, and the influences of the reaction were proposed.
