A novel and efficient method has been developed for synthesizing benzothioamide from benzonitrile in supercritical CO2, which could be used to synthesize various benzothioamide derivatives efficiently with yields of up to 98% without the need for organic solvent. Notably, some H2S-based salts were designed and prepared, and they were found to be effective catalysts in promoting the thiolysis of benzonitrile to produce benzothioamide in an excellent yield. Furthermore, the utilization of supercritical CO2 as a solvent has demonstrated a remarkable increase in the yield of the desired product compared to conventional solvents for promoting benzonitrile thiolysis. Additionally, the investigation of the reaction mechanism has revealed that the acid–base properties of the reaction solution played a crucial role in the thiolysis of benzonitrile mediated by the H2S-based salts.
