title: Nickel-catalyzed 1,4-addition of trialkylboranes to alpha,beta-unsaturated esters: dramatic enhancement by addition of methanol.
abstract: [reaction: see text] Nickel catalyst systems for 1,4-addition of trialkylboranes to alpha,beta-unsaturated esters have been developed. Addition of methanol was found to be essential for the alkylation reaction with 9-alkyl-9-BBNs.
