Description and Uses

TBTA was introduced shortly after the copper-catalyzed azide-alkyne cycloaddition reaction was discovered to mitigate thermodynamic instability of Cu(I) in aerobic media. TBTA is a water-insoluble ligand and must be first dissolved in DMSO or DMF. J Am Chem Soc., 143 (18), 6787-6791. T. R. Chan, R. Hilgraf, K. B. Sharpless, V. V. Fokin, Org. Lett. 2004, 6, 2853.

Tris-(benzyltriazolylmethyl)amine is a useful reagent for copper (I) catalyzed azide-alkyne cycloadditions.?It can also be used for postsynthetic labelling of alkyne-modified DNA.
