Chemistry Letters, 19 8 1 1665 the same ones in rather good yields (Run 20 and 21 in Table 1). On the other hand, the reaction with тг -electron-deficient aromatic compounds such as methyl benzoate occurred in acetonitrile at 82°C in the presence of pyridine. Similarly to FITS, perfluoroalkylphenyliodonium sulfate (FIS)D^ reacted with various aromatic compounds to give the products (Scheme 2). The results and re- action conditions are shown in Table 2, As a whole, the reactivity of FIS is ...
