Molecular Organization of Reagents in the Kinetics and Catalysis of Liquid-Phase Reactions: XIII. Cyclic Transition States Involving Solvent Molecules in the Mechanism of Aminolysis of Cyclocarbonates in an Alcohol Medium

Trends in the influence of a proton-donor solvent on the reaction of aminolysis of ethylene carbonate, which proceeds through concerted and stepwise mechanisms, are studied. The study is based on kinetic data of model reactions in alcohol solutions and results of DFT quantum chemical calculations of reaction paths that involve hydrogen-bonded transition states and intermediates containing different numbers of solvent molecules in the...
