A method for the synthesis of cyclobuta aromatic compounds by cyclizing two ortho dibromoalkyl substituents is described. Using a mediator, such as nickel metal, and continuous removal of product from contact with the mediator, high product yields are achieved. A method for bromination of ortho alkyl substituents of aromatic compounds is also described.
