Abstract: The compound boron carbide, B4C, is an effective catalyst for the synthesis of aromatic esters by reacting benzoyl halides with phenols in the presence of powdered B4C.
Abstract: The compound boron carbide, B4C, is an effective catalyst for the alkylation and acylation of aromatics to produce polybenzyls, ketones, esters and alkyl benzenes. The catalyst boron carbide is also effective in conducting intramolecular Friedel-Crafts type reactions to produce cyclic ketones.
