The purple‐coloured iron peroxo complex [Fe(III)EDTA(η2‐O2)]3− as a novel reagent system for Pd‐catalyzed decarboxylative ortho‐acylation of acetanilides with α‐oxocarboxylic acids at roomtemperature in aqueous media has been realized. This reaction provides an effective access to ortho‐acylacetanilides under mild conditions.

influence of the substitution on indolylmagnesium salts in the reaction with benzoyl chlo ride, acrylonitrile and methyliodide, giving the C- and N-derivatives, have been carried out. The yield in the C- and N-product depends upon the electronic character and position of the substituent (methyl or phenyl) on the indole ring and of the ethereal solvent as well as the concentration and molar ratio of the reagents

Treatment of 3-(2-aminophenyl)-2-propenyltriphenylphosphonium bromide with acid anhydride and tertiary amine affords 1,3-diacylindoles in yields ranging from 22 to 64%. A plausible mechanism of this new cyclization reaction is described.
