Iridium complex-catalyzed cross-coupling reaction of terminal alkynes with internal alkynes via C-H activation of terminal alkynes

The cross-dimerization of an electron-rich terminal alkyne with an electron-deficient internal alkyne was promoted by an iridium complex to produce a 1:1 adduct in high regio- and stereoselectivities. This reaction was extended to various combinations of
