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.
在催化量的Cu(OTf)2和Sn(OTf)2存在下,研究了烷基化,酰化,苯甲酰化和磺酰化等芳香亲电取代反应。Cu(OTf)2对于烷基化,酰化和苯甲酰化反应非常有效。然而,在磺酰化反应的情况下,Sn(OTf)2给出了更好的结果。
