Abstract
Palladacycles derived from phenone-oximes 1 are efficient precatalysts for the Suzuki– Miyaura coupling of arylboronic acids with aromatic and heteroaromatic bromides and chlorides under water reflux under aerobic conditions. Alternatively, the coupling can also be carried out at room temperature in methanol–water. Aryl bromides gave biaryls with TON up to 105 and TOF up to 7× 104 h− 1. Activated and deactivated aryl chlorides need the ...
