摘要

In this paper, a new synthetic protocol for one-pot preparations of 5-halo-l,4-disubstituted-l,2,3-triazoles is provided by rational combination of a Cu1 catalyzed azide-alkyne cycloaddition (CuAAC) reaction and an oxidative halogenation reaction. Cul- N-chlorosuccinimide (NCS) and CuBr-NCS reaction systems are developed, respectively, for effective preparations of 5-iodo-l,4-disubstituted-l,2,3-triazoles and 5-bromo-l,4-disubstituted-l,2,3-trizoles under mild conditions with a high tolerance of various sensitive groups.
