Chemical transformation with vinylenecarbonate as an emerging synthetic unit has recently attracted considerable attention. This report is a novel conversion pattern with vinylenecarbonate, in which such a vibrant reagent unprecedentedly acts as a difunctional coupling partner to complete the C–H annulation of free anilines. From commercially available substrates, this protocol leads to the rapid
