PRODUCTION OF POLYACYLATED AROMATIC COMPOUND

摘要

Preparation of polyacylated aromatics of the general formula I in which the variables have the following meaning: R<1> is phenyl or phenyl carrying inert substituents, or alpha -halo-C1-C6-alkyl, where these radicals can be identical or different; R<2> is C1-C4-alkyl; m is 2 or 3; n is 0 to 4, where the substituents R<2> can be different if n > 1, with the proviso that m + n in which p stands for 1 or 2, with an amount corresponding to the desired degree of acylation of a carboxylic acid halide of the general formula III in which X stands for halogen, in the presence of Fe(II), Fe(III), Zn(II), Mo(VI), W(VI) or Sn(IV) compounds.
