Gold(III) chloride catalyzed direct amination of arenes with azodicarboxylates was developed. The new catalytic system was active to a broad range of substrates, and the reaction was carried out under mild conditions. It represents the first catalytic system for the direct amination of electron-deficient arenes with azodicarboxylates to the best of our knowledge. This reaction provides an important

An efficient cross coupling amination of arene with azodicarboxylate to afford hydrazides catalysed by ruthenium chloride has been demonstrated. The catalyst was found to be effective across a spectrum of arenes with a variety of functional groups. The yields are found to be modest to low depending on the type of substrates. The catalyst can be recycled in ligand free conditions to afford the cross
chloride-catalyzed direct amination of electron-richarenes with azodicarboxylates gives the corresponding aryl hydrazides in moderate to good yields within two minutes under mild conditions. This method will serve as an important tool for the synthesis of bioactive nitrogen-containing products and pharmaceuticals. Iron(III) chloride-catalyzed direct amination of electron-richarenes with azodicarboxylates gives the
