Product Information
- 4-chloro-1H-benzimidazole
4-Chloro-1H-benzimidazole is a synthetic nucleophile that reacts with thioethers to form an ion pair. It can be used as a precursor for the synthesis of captopril, an antihypertensive drug. 4-Chloro-1H-benzimidazole is also known to react with carboxylic acids to form ion pairs and then dehydrate to form electrostatically bound products. The reaction mechanism starts with the nucleophilic attack of a proton on the carbonyl carbon atom in the carboxylic acid, forming an intermediate carbocation which reacts with a chloride ion. This intermediate then collapses and forms two products: one positively charged and one negatively charged. The positively charged product is a chloroformate salt while the negatively charged product is an alcohol.
