Trichloroacetimidates are useful reagents for the synthesis of esters under mild conditions that do not require an exogenous promoter. These conditions avoid the undesired decomposition of substrates with sensitive functional groups that are often observed with the use of strong Lewis or Brønsted acids. With heating, these reactions have been extended to benzyl esters without electron-donating groups. These inexpensive
三氯乙亚氨酸酯是在温和条件下合成酯的有用试剂,不需要外源促进剂。这些条件避免了带有敏感官能团的底物发生不希望的分解,这种分解通常在使用强路易斯酸或布朗斯台德酸的情况下观察到。通过加热,这些反应已扩展为不具有给电子基团的苄基酯。这些廉价且方便的方法应在复杂基质中酯的形成中找到应用。
