In a new benzylation protocol, various 1,2,3,4-tetrahydroquinolines were efficiently converted in combination with aryl aldehydes into β-benzylated quinolines by employing readily available [RuCl2(p-cymene)]2 as a catalyst and O2 as a sole green oxidant. This step- and atom-economic reaction offers excellent functional group tolerance and chemoselectivity.
