Catalytic Mechanisms of Acyl Transfer Reactions in Dipolar Aprotic Media. 2. Electrophilic Activation of the Carbonyl Group by Quaternary Alkylammonium and Imidazolium Functions

Article abstract of DOI:10.1021/ja00410a035

Crown ether solvated potassium acetate in dipolar aprotic media readily converts p-nitrophenyl o-toluate to the corresponding acetyltoluyl mixed anhydride.The reaction proceeds at room temperature in quantitative yield.The rate of acyl transfer is 0.0118
