Facile route for N1-aryl benzotriazoles from diazoamino arynes via CuI-mediated intramolecular N-arylation

A facile and high-yielding protocol for diverse benzotriazoles through intramolecular N-arylation of different o-chloro-1,2,3-benzotriazenes using CuI/Cs2CO3 has been developed.

A facile and high-yielding protocol for diverse benzotriazoles through intramolecular N-arylation of different o-chloro-1,2,3-triazenes using CuI/Cs2CO3 has been developed under mild reaction condition.
