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.
Claims7
An improved process for preparing derivatives of mercaptophenols containing nitrile, carbonyl, sulphone or ester groups by reacting a mercaptophenol with a vinyl compound containing a conjugated nitrile, carbonyl, sulphone or ester group said process characterized by reacting said mercaptophenol and said vinyl compound in a polar solvent with an amine catalyst.
