capable of effecting the rapid, room-temperature cross-coupling between acid fluorides and diorganozincreagents. 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
