Triazole derivativesR 0280 Ruthenium-Catalyzed Cycloaddition of Alkynes and Organic Azides. —
1,5-Disubstituted and 1,4,5-trisubstituted 1,2,3-triazoles are prepared by the title reaction in good yields and with high regioselectivity. Together with the known Cu(I)-catalyzed azide—alkyne cycloaddition reaction affording 1,4-disubstituted 1,2,3-triazoles, both regioisomers of disubstituted 1,2,3-triazoles are available. — (ZHANG, L.; CHEN, X.; XUE, P.; SUN, H.
