ABSTRACT:
An improved process for preparing derivatives of mercaptophenols containing nitrile, carbonyl, sulphone or ester groups characterized by reacting the components in a polar solvent with an amine catalyst. The catalyst can be removed from the product by co-distillation with the solvent to leave a relatively pure product free of contaminant without the need for further purification steps. The preferred amine catalysts are tertiary amines.
