Rp. Singh et al., An efficient method for aromatic Friedel-Crafts alkylation, acylation, benzoylation, and sulfonylation reactions, TETRAHEDRON, 57(1), 2001, pp. 241-247
Aromatic electrophilic substitution reactions such as alkylation, acylation
, benzoylation, and sulfonylation were studied in the presence of a catalyt
ic amount of Cu(OTf)(2) and Sn(OTf)(2). Cu(OTf)(2) was very efficient for a
lkylation, acylation, and benzoylation reactions. However, in case of sulfo
nylation reactions, Sn(OTf)(2) gave better results. (C) 2000 Elsevier Scien
