【 摘 要 】

A selective synthetic method of the 2,5-biaryltriazolones has been developed via copper-catalyzed N-arylation reaction. Aryltriazolones, which were readily prepared from commercially available compounds, were N-arylated to 2,5-biaryltriazolones with high regioselectivity. This approach allows for access to a variety of 2,5-biaryl-1,2,4-trizol-3-ones in a simple and practical manner.
