Abstract
Benzimidazoles were synthesized by the reaction of o-phenylenediamine phosphate with fatty acids in solvent-free under reflux.The structure were confirmed by IR.The optimal reaction conditions from orthogonal experiment were as follows:o-phenylenediamine was 50 mmol,n(o-phenylenediamine):n(formic acid) was 1.0:1.5,phosphate was 4 g,reaction time was 7 h.
