AgF-Mediated Electrophilic Amination of Alkoxyarylsilanes with Azodicarboxylates.

A facile and efficient AgF-mediated electrophilic amination of alkoxyarylsilanes with azodicarboxylates was developed. The reaction proceeds in green solvent under simple and mild conditions to generate the corresponding aryl hydrazines. AgF acts both as a stoichiometric fluoride source and a reagent for transmetalation to the arylsilver intermediate that eventually reacts with azodicarboxylates to provide aryl hydrazines.
