A nickel-catalyzed Negishi coupling of cyclobutanone oxime esters with aryl zinc reagents has been developed, in which nickel serves both as an initiator for imine radicals and a catalyst for the coupling of aryl zinc reagents with oxime esters. The protocol can avoid the use of poisonous cyanide and has broad substrate scope as well as good functional group compatibility. Therefore, this method provides an attractive strategy for the synthesis of valuable nitriles. Preliminary mechanistic studies indicate that a radical pathway is involved in the product formation.

Key words: Negishi coupling, nickel, cyclobutanone oxime esters, aryl zinc reagents
