An efficient and convenient synthesis of 2,2,2‐trichloroethyl (TCE) aryl‐ and vinyldiazoacetates was achieved by palladium‐catalyzed cross‐coupling reactions between TCE diazoacetates and aryl or vinyl iodides. The broad substrate scope allows for rapid and facile formation of TCE aryl‐ and vinyldiazoacetates, which recently have emerged as versatile reagents for rhodium‐carbene chemistry.
通过TCE重氮乙酸酯与芳基或乙烯基碘化物之间的钯催化交叉偶联反应,可以高效,方便地合成2,2,2-三氯乙基(TCE)芳基和乙烯基重氮乙酸酯。广泛的底物范围允许快速简便地形成TCE芳基和乙烯基重氮乙酸酯,最近它们已成为铑卡宾化学的多功能试剂。
