A new method for the directed meta acylation of aromaticcompounds is described. This method involves an ortho lithiation procedure combined with zirconocene−benzyne chemistry. 3-Acyl-1-substituted benzene derivatives were obtained by acidic hydrolysis of the azazirconacycle intermediate which results from the coupling of a nitrile with a zirconocene−benzyne complex. Similarly, 3-acyl-2-iodo-1-substituted
