Buckley, Benjamin Dann, Sandie Harris, Daniel P. Heaney, Harry Stubbs, Emma C. Alkynylcopper(I) polymers and their use in a mechanistic study of alkyne-azide click reactions Polymeric dinuclear alkynylcopper(I) complexes, for example phenylethynylcopper(I), can be prepared by a robust method involving the interaction of terminal alkynes with copper(II) salts in acetonitrile. The use of the ladder polymers provides heterogeneous catalysts for copper-catalyzed azide–alkyne cycloaddition (CuAAC) reactions and provides important mechanistic information. untagged;Chemical Sciences not elsewhere classified 2014-01-14
