A series of well‐defined copper(I) complexes bearing ring‐expandedN‐heterocyclic carbene (NHC) ligands has been applied to the azide–alkyne cycloaddition reaction. The obtained results notably showed that the six‐membered NHC ligands outperform well‐established five‐membered ones. [CuI(Mes‐6)] displayed a remarkable catalytic activity while respecting the strict criteria for click reactions.
A highly efficient copper(i) catalyst for the 1,3-dipolar cycloaddition of azides with terminal and 1-iodoalkynes in water: regioselective synthesis of 1,4-disubstituted and 1,4,5-trisubstituted 1,2,3-triazoles
A new water soluble Cu(I) complex that exhibits a versatile and high catalytic activity in the Huisgen cycloadditions of azides and terminal alkynes in aqueous media under mild conditions is the first well-defined Cu(I) catalyst that is active with 1-iodoalkynes in water under aerobic conditions.
Efficient consecutive 1,2,3-triazole formations using multiazide platforms are disclosed. On the basis of unique clickability of the 1-adamantyl azido group, a four-step synthesis of tetrakis(triazole)s was achieved from a tetraazide platform molecule. This method was applied to a convergentsynthesis of tetrafunctionalized probes in a modular synthetic manner.
