Aromatic electrophilic substitution reactions such as alkylation, acylation, benzoylation, and sulfonylation were studied in the presence of a catalytic amount of Cu(OTf)(2) and Sn(OTf)(2). Cu(OTf)(2) was very efficient for alkylation, acylation, and benzoylation reactions. However, in case of sulfonylation reactions, Sn(OTf)(2) gave better results. (C) 2000 Elsevier Science Ltd.
