An arrested migration of a hydrido ligand from a ruthenium center to a μ‐η 1 ,η 2 ‐bound alkenyl group results in the bonding mode in the products 2 of the reaction of terminal alkynes HCCR with 1 . These products can be considered to represent the last step of the hydrogenation of an alkyne to an alkene at a heterobimetallic center. R = Ph, CH 2 Ph, CH 2 OMe, CH 2 OH.
