Abstract

Abstract A convenient and useful esterification was realized, and this reaction proceeded without a dehydrating reagent or water removal equipment. A series of ortho-hydroxyphenyl carboxylic acids and benzoic acids were transformed to their corresponding methyl esters under CAN/CH 3 OH reaction conditions. Whereas in an aprotic solvent, acetonitrile, sp 3-C tethered ortho-hydroxyphenyl carboxylic acids undergo simultaneous o, p-dinitration and ...
