An oxidative annulation for the synthesis of 2,4-diarylquinolines from o-allylanilines is disclosed that uses recyclable reagent Chloranil as the oxidant. The corresponding products are obtained in moderate to excellent yields. Furthermore, a one-pot access to 2,4-diarylquinolines from easily available anilines and 1,3-diarylpropenes is described as a highly atom-efficient protocol that involves
