| Abstract: | Synthesis of bifunctional thiols (2-alkylmercaptobenzimidazoles) and kinetic studies of the catalysis of the hydrolysis of p-nitrophenylacetate by these compounds, and by seven thiols indicates high activity of the 2-mercaptomethylbenzimidazoles in their neutral form, interpreted as the result of nucleophilic catalysis by the thiol function in its neutral state combined with general basic catalysis by the heterocycle. |
