Copper catalysis for triazines

Abstract This review summarizes the data on the synthesis and modification of various triazine derivatives using a copper additive as catalyst or mediator. The first part is devoted to the synthesis of 1,3,5-, 1,2,4- and 1,2,3-triazines from suitable amidine, hydrazide, hydrazone, azide, and amide derivatives and 1,3-dipoles as well as via ring extension of pyrazole, while the second part discusses modification of triazines using Sandmeyer, Sonogashira, Liebeskind-Srogl, Ullmann, and other types of reactions.
