Abstract
1. It has been shown by quantum-chemical calculations that the monomolecular decomposition of tert-butyl esters ot carboxylic acids, which involves the detachment of isobutylene, takes place as the result of the transfer of a proton from the closest CH3 group of the tert-butyl substituent to the carbonyl O atom. 2. The catalytic action of carboxylic acids on this reaction is exhibited by the transfer of a proton from the COOH group taking place in the reaction complex formed by the ester and the acid with a lower consumption of energy than the migration of a proton from the CH3 group in a monomolecular reaction.
