capable of effecting the rapid, room-temperature cross-coupling between acid fluorides and diorganozinc reagents. The use of acid fluorides as electrophilic partners allows this reaction to tolerate epimerizable functionality as well as beta leaving groups. The same catalyst is also capable of cross-coupling acid chlorides, acyl cyanides, anhydrides, thioesters, and pyridyl esters. Noteworthy is the
我们已经确定了一种能够在酰氟和二有机锌试剂之间实现快速、室温交叉偶联的催化剂。使用酰基氟作为亲电伙伴允许该反应耐受差向异构官能团以及β离去基团。相同的催化剂还能够交叉偶联酰氯、酰基氰化物、酸酐、硫酯和吡啶酯。值得注意的是反应成功地从有机金属片段转移两个基团的能力。
