propargylic alcohols with aryl chlorides has been developed. The reaction occurs smoothly in neat water with 2 mol% PdCl2 as catalyst, and various synthetically useful functional groups, including ether, aldehyde, ketone, and heterocyclics, are well tolerated. Moreover, the reaction could proceed through a consecutive Sonogashira/deacetonative process using 2-methyl-3-butyn-2-ol and aryl chlorides as coupling
摘要 开发了一种钯催化芳炔醇与芳基氯去乙酰偶联的高效绿色工艺。该反应在纯水中以 2 mol% PdCl2 为催化剂平稳进行,各种合成有用的官能团,包括醚、醛、酮和杂环,都具有良好的耐受性。此外,该反应可以通过使用 2-methyl-3-butyn-2-ol 和芳基氯作为偶联伙伴的连续 Sonogashira/deacetonative 过程进行,以良好的收率提供对称炔烃。图形概要
