Potassium Carbonate to Unlock a GaCl 3 -Catalyzed C-H Propargylation of Arenes

Abstract : A gallium-catalyzed C-H propargylation of arenes using bromoallenes is described. The development of this new reaction was first hampered by a side hydroarylation process catalyzed by adventitious protons, easily generated from the solvent (1,2-dichloroethane).
