Abstract

The development of an iridium-catalyzed regio- and stereoselective dimerization process has enabled the formation of (Z)-enyne products. More specifically, low catalyst loadings of an iridium(I) complex, featuring a bulky N-heterocyclic carbene-phosphine ligand combination, has been successfully employed in this selective head-to-head dimerization of terminal alkynes via C-H activation.
