Abstract
The present invention provides a novel process for preparing a substituted aromatic compound such as an aromatic halo compound or a salt thereof through a transformation reaction of an aromatic diazonium salt from an aromatic amino compound at stable high yields utilizing a novel Sandmeyer-like reaction using a nitroxide radical compound as a reaction catalyst.
