摘要

The optimization, substrate scope, and mechanism of esterification and amidation of carboxylic acids mediated by imidazole-based reagents are discussed. The innate reactivity of carbonylimidazole reagents with a range of nucleophiles is also explored. New reagents developed for the synthesis of α, β-unsaturated esters are described, as are reagents for the preparation of tertiary amides directly from carboxylic acids.
