Palladium-catalyzed substrate-switchable C–H alkenylation and alkylation of benzoic acids using MBH alcohols†
Abstract
Pd-catalyzed carboxylate-directed C–H alkenylation and alkylation of benzoic acids has been achieved by switching the MBH alcohol used as the coupling partner. The alkenylation results in the formation of aryl acrylaldehydes, whereas the alkylation furnishes the formation of α-benzyl β-ketoesters.
