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 o-dichlorobenzene
as solvent. Specific di- and triketones are obtained
in good to excellent yields (45-83%).
