    • a's of the oxygen and sulfur atoms, this would imply that the protonated oxygen and sulfur leaving groups depart with the same rates. This is highly unlikely. (2) The reviewer's explanation of the N-methylmorpholinium catalysis violates the principle of microscopic reversibility because the trapping of the thiolate ion would lead to a rate reduction in the nucleophilic addition direction, whereas the observed buffer catalysis means that the reaction is accelerated in both directions.
