Abstract
Disclosed is a Lewis acid catalyst composition comprising a specific mixed medium and a Lewis acid catalyst (II), wherein the specific mixed medium is mixed medium (I) comprising a perfluorinated aliphatic hydrocarbon (A) and at least one non-fluorinated hydrocarbon or a mixed medium (I′) comprising a perfluorinated aliphatic hydrocarbon (A), a perfluorinated aromatic hydrocarbon (C) and water (D), and wherein the Lewis acid catalyst (II) is at least one compound selected from the group consisting of compounds respectively represented by the following formulae (1), (2) and (3): (RfSO3)nM (1), [(RfSO2)2N]nM (2), and [(RfSO2)3C]nM (3). Also disclosed is a Lewis acid catalyst represented by the above-mentioned formula (3).
