    Abstract: An anilide is reacted with an acylating agent by using as a catalyst a tri(perfluoroalkane sulfonate) compound of any of the elements belonging to groups 3 to 5 and groups 13 to 15 in periods 4 to 6 of the periodic table, thereby bonding an acyl group to the benzene ring. Thus, ketoaniline derivatives, which are useful as physiologically active compounds or intermediates in synthesizing the same, are synthesized in high reaction yield by catalytic acylation.
