Abstract
The present invention relates to a process for the synthesis of haloalkylferrocenes, comprising a first stage of reaction, in the presence of AlCl.sub.3 as catalyst and in organic solvent medium, of a carboxylic acid halide or anhydride with ferrocene or an alkylferrocene. After this stage, without prior isolation of the intermediate compound, a metal hydride is added to the reaction mixture. The haloalkylferrocenes are particularly useful as intermediates in the synthesis of combustion catalysts for propellants.
