| abstract | R¹ Phenyl oder inerte Substituenten tragendes Phenyl, α-Halogen-C₁-C₆-Alkyl, wobei diese Reste gleich oder verschieden sein können; R² C₁-C₄-Alkyl; m 2 oder 3; n 0 bis 4, wobei die Substituenten R² verschieden sein können, wenn n >1 ist, mit der Maßgabe, daß m + n ≦ 6 ist, indem man einem Arylaromaten der allgemeinen Formel IIn n in der p für 1 oder 2 steht, mit einer dem gewünschten Acylierungsgrad entsprechenden Menge an einem Carbonsäurehalogenid der allgemeinen Formel IIIn n in der X für Halogen steht, in Gegenwart von Fe(II)-, Fe(III)-, Zn(II)-, Mo(VI)-, W(VI)- oder Sn(IV)-Verbindungen umsetzt.Production of multi-acylated aromatics of the general formula I in which the variables have the following meaning: R¹ Phenyl or phenyl which carries inert substituents, α-halogeno-C₁-C₆-alkyl, where these radicals can be the same or different; R² C₁-C₄ alkyl; m 2 or 3; n 0 to 4, where the substituents R² can be different if n> 1, with the proviso that m + n ≦ 6 by using an aryl aromatic of the general formula II in which p represents 1 or 2, with an amount of a carboxylic acid halide of the general formula III corresponding to the desired degree of acylation in which X represents halogen, in the presence of Fe (II), Fe (III), Zn (II), Mo (VI), W (VI) or Sn (IV) compounds. |
