The remarkable feature of this work was using green, non-toxic PEG-400 as a carbon synthon for highly selective synthesis of quinolines (quinoxalines) and methylquinolines (methylquinoxalines) under metal-free conditions.

A palladium‐catalyzed cross‐coupling between aryl carboxylates and boronicacids has been achieved for the first time by taking advantage of the enhanced reactivity of quinoline 4‐carboxylates. Also for the first time a Suzukicouplingreaction via a self‐activation of boronicacids without addition of base is described. The reactions proceed under mild conditions (25–65 °C) to give excellent yields
