Explain the following laws within the … WebThe carboxylic acid formed by mono-acylation has lower reactivity than the acid anhydride or the acyl chloride as a reagent for acylation. Con-sequently, further acylation is expected to be difficult. To confirm this prediction, acylation with phthalic acid was examined (Entry 8). The amount of di-FC was small as expected.
