Abstract

Ni(COD)2/PCy3 is a versatile catalyst for the cross-coupling of a diversity of aryl neopentylglycolboronates with aryl and heteroaryl mesylates and sulfamates containing both electron-donating and electron-withdrawing substituents in THF at room temperature. This Ni-catalyzed cross-coupling tolerates electrophilic functionalities sensitive to organolithium and organomagnesium compounds.
