Zusammenfassung:The present disclosure provides a process for preparing an aryl ketone of Formula I, comprising reacting a substituted benzene of Formula II with a carboxylic acid of formula IIIa and/or a carboxylic anhydride of formula IIIb in presence of an alkyl sulfonic acid acting as catalyst cum solvent/contacting medium. I, II, IIIa, IIIb, wherein, R1, R2, R3 and R4 are as defined in the description. La présente invention concerne un procédé de préparation d'une arylcétone de formule I, comprenant la réaction d'un benzène substitué de formule II avec un acide carboxylique de formule IIIa et/ou un anhydride carboxylique de formule IIIb en présence d'un acide alkylsulfonique agissant comme milieu de catalyseur cum solvant/de contact. I, II, IIIa, IIIb, dans lesquelles, R1, R2, R3 et R4 sont tels que définis dans la description.
