Abstract
Stannous chloride dihydrate is used as an efficient catalyst in reductive cyclization of 2-nitro-5-substituted aniline Schiff base leading to stable 2,5-disubstitued benzimidazole derivatives in excellent yields with good purity. It provides a novel method of synthesis of 2,5-disubstitued benzimidazole under reductive system at room temperature.
