    Abstract: A solid acid catalyst with which a reaction proceeding with a BrFnsted acid or Lewis acid catalyst is efficiently conducted, for example, the benzoylation of an alcohol can be easily conducted, and which can be easily recovered and reused. The solid acid catalyst is excellent from the standpoints of toxicity, environment, etc. An arylbis(perfluoroalkylsulfonyl)methane represented by the general formula [1] (wherein R represents (un)substituted aryl and Rf and Rf each independently represents perfluoroalkyl), e.g., pentafluorophenylbis(perfluoroalkylsulfonyl)methane, is fixed to a polystyrene resin through bonding in the para-position to thereby obtain a polystyrene-supported arylbis(perfluoroalkylsulfonyl)methane represented by the general formula [3] (wherein R represents (un)substituted arylene and Rf and Rf are the same as defined above).

    Abstract: Disclosed is a method of chlorinating the side chains of an aromatic compound having general formula (I) where each R is independently selected from R' or OR', each R' is independently selected from alkyl from C1 to C6, and n is an integer from 1 to 3. Some of the aromatic compound is incompletely alpha -chlorinated using about 0.1 to about 0.6 equivalents of chlorine per equivalent of the aromatic compound. The alpha -chlorinated aromatic compound is separated from unreacted aromatic compound and the alpha -chlorinated aromatic compound is further chlorinated. The two step chlorination of the aromatic compound reduces ring chlorination.
