Resumen:
The exceptional leaving group ability of the trimethylstannyl group in electrophilic aromatic substitutions makes possible the synthesis, in a single step, of bi- and triaroylarenes through the catalyst-free, regioselective reaction of bi- and tristannylarenes with different aroyl halides in ortho-dichlorobenzene as solvent. Specific di- and triketones are obtained in good to excellent yields (45% - 83%).
