1,7-palladium migration via C-H activation, followed by intramolecular amination: Regioselective synthesis of benzotriazoles
A novel 1,7-palladiummigration-cyclization-dealkylation sequence for the regioselective synthesis of benzotriazoles has been developed. These reactions proceed in excellent yields with high regioselectivities. The mechanism of the reaction has also been investigated.
