Ruthenium-Catalyzed <i>trans</i>-Hydroalkynylation and <i>trans</i>-Chloroalkynylation of Internal Alkynes

Abstract

-addition mode. The well-balanced affinities of the different reaction partners to the ruthenium catalyst ensure that crossed addition prevails over homodimerization of the individual components, as can be deduced from spectroscopic and crystallographic data of various intermediates; this includes a dinuclear complex in which an internal alkyne bridges two [Cp*RuCl] fragments.
