all the hype: An oxidative dimerization reaction of aromatic amines utilizing tert‐butyl hypoiodite (tBuOI) under mild reaction conditions leads to aromatic azocompounds (see scheme). The method allows access to unsymmetric aromatic azocompounds, which are difficult to prepare by conventional synthetic methods, in a selective manner.
