Copper(I) complexes as catalysts for the synthesis of N-sulfonyl-1,2,3-triazoles from N-sulfonylazides and alkynes.
The well-defined complex [Tpm(*,Br)Cu(NCMe)]BF(4) efficiently catalyses the [3+2] cycloaddition between alkynes and N-sulfonylazides under mild conditions, with conversions comparable to others obtained with in situ generated catalytic systems previously described for this transformation.
