CO2 Improved Synthesis of Benzimidazole with the Catalysis of a New Calcium 4-Amino-3-hydroxybenzoate
{{output}}
In this paper, we explored the synthesis of benzimidazole by the reaction of DMF and o-phenylenediamine. In the process of catalyst screening, we found that 4-amino-3-hydroxybenzoic acid, benzoic acid, and benzene-1,3,5-tricarboxylic acid could catalyze the re... ...
