A nickel catalyst for the addition of organoboronate esters to ketones and aldehydes
A Ni(cod)2/IPr catalyst promotes the intermolecular 1,2-addition of arylboronate esters to unactivated aldehydes and ketones. Dlaryl, alkyl aryl, and dialkyl ketones show good reactivity under mild reaction conditions (3) with aryl ether substrates. A Ni(0)/Ni(II) catalytic cycle initiated by the oxidative cyclization of the carbonyl substrate Is proposed.
