WebAs one of the most common click reactions, strain-promoted alkyne-azide cycloaddition (SPAAC) does not require the use of metal catalysts, reducing agents or stable ligands. On the contrary, the reaction uses the enthalpy released from the ring stress to cyclooctyne to form stable triazole. Introduction SPAAC can be carried out efficiently. Web5 Oct 2024 · The click chemistry reactions Sharpless and Meldal developed involved copper, however, which is often toxic to living cells.
