Abstract
A series has been established for the relative activity of catalysts and 4-substituted benzoyl chlorides on acylation of benzothiazolin-2-ones with 4-substituted benzoyl chlorides in the presence of FeCl3, FeCl3·6H2O, FeCl3⋅12H2O, ZnCl2, ZnCl2⋅2H2O, AlCl3, and iron acetylacetonate, as a function of the degree of acidity of the catalyst and the electrophilicity of the acylating agent.
