Synthesis of Deuterated 1,2,3-Triazoles [PDF]
The Journal of Organic Chemistry, 2012 The copper-catalyzed azide-alkyne cycloaddition (CuAAC) is a highly effective method for the selective incorporation of deuterium atom into the C-5 position of the 1,2,3-triazole structure. Reactions of alkynes and azides can be conveniently carried out in a biphasic medium of CH(2)Cl(2)/D(2)O, using the CuSO(4)/Na ascorbate system. The mildness of the
