An eco-friendly and readily accessible 2,2,6,6-tetramethylpiperidinium triflate was found as highly-selective and self-separated catalyst for esterification under solvent-free condition. The X-ray crystallography revealed that it formed a ‘hydrophobic wall’ which could effectively eliminate the generated water from the reactive sites. Moreover, it could precipitate from the reaction system with excellent

is greatly economically influential. We developed a non-expensive cobalt-catalyzed multicomponent carbonylative reaction for the synthesis of γ-aryl carboxylic acid esters from readily available methylarene, ethylene, and CO, which are widely found in multiple FDA-approved drugs.
将原材料直接转化为精细化学品具有很大的经济影响。我们开发了一种廉价的钴催化多组分羰基化反应,用于从容易获得的甲基芳烃、乙烯和 CO 合成 γ-芳基羧酸酯,这些物质广泛存在于多种 FDA 批准的药物中。
