Facile synthesis of N²-substituted-1,2,3-triazole from aryl ethynylene and azide via a one-pot two-step strategy

An efficient one-pot two-step synthetic strategy to access highly selective N²-substituted-1,2,3-triazole from aryl ethynylenes, azides and furan has been developed via a radical transformation. 17 examples of aryl ethynylene with various substituents were converted into their corresponding functionalized N²-substituted-1,2,3-triazole derivatives in good yields.
