Selective Buchwald–Hartwig arylation of<i>C</i>-amino-1,2,4-triazoles and other coordinating aminoheterocycles enabled by bulky NHC ligands and TPEDO activator

Abstract

A facile method for selective N-(hetero)arylation of coordinating 3(5)-amino-1,2,4-triazoles under Pd/NHC catalysis using TPEDO as a new efficient Pd( ii ) to Pd(0) reductant has been developed.
