Ethanol Initiates Reactions Using Microwaves. A Technique for Aromatic Ester Synthesis
摘要:
Orthophthalic monoesters were synthesized through-a reaction between phthalic anhydride and potassium phenoxides. Synthesis was performed by irradiating pastes containing organic reagents and a small quantity of ethanol.

functions as a selective oxidant for the transformation of arenes to phenols under mild conditions. Although the reaction proceeds through a radical mechanism, aromatic C–H bonds are selectively oxidized in preference to activated –H bonds. Notably, a wide array of functional groups are compatible with this reaction, and this method is therefore well suited for late-stage transformations of advanced

with beta = 0.46. The kinetics of the hydrolysis of the esters were studied below pH 6.20, and the mechanism involves the formation of phthalicanhydride, which then is hydrolyzed to the phthalic acid. Phenoxide ion has a very high rate constant for the reaction with phthalicanhydride, so above pH 6.20 it competes significantly with the hydrolysis of the anhydride. The reactions of the esters as a function
