Hofmann N‐alkylationAn efficient method for the N‐alkylation of poorly nucleophilic amines using ferric perchlorate immobilized on SiO2 as a catalyst is described. Fe(ClO4)3 was prepared from mixing iron(III) hydroxide and perchloric acid and adsorbed on silica gel. The catalyst was characterized...
