2-Amino-2′-hydroxybenzophenones 3 have been synthesized by acylation of phenols with 2-isocyanatobenzoyl chloride 2 in the presence of aluminium trichloride. The ring-chain tautomerism of the reagent 2 promoted by Lewis acid has been established on the basis of a crystal structure analysis of the 1:1 complex formed by 2 and aluminium trichloride.
