Nucleophilic Acyl Substitution Nucleophilic Acyl Substitution is a major reaction for acids and acid derivatives. This is the reaction that converts one derivative into another. The substitution can occur in basic or acidic condition, depending on a derivative.

Mechanism. (Similar to Smith, 20.72) The existence of a tetrahedral intermediate in nucleophilic acyl substitution is supported by a series of experiments carried out by Myron Bender in 1951. In the key experiment, Bender carried out the following base catalyzed hydrolysis of ethyl benzoate, where the carbonyl oxygen was labeled with "0. Bender recovered some starting material from this reaction mixture where the carbonyl oxygen was no longer labeled. Propose a mechanism that explains this observation. Do we on Mechanism...
