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

Abstract

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.
