A selective Ru-catalyzed semireduction of alkynes to Z olefins under transfer-hydrogenation conditions.
By using a readily available, air- and moisture-stable dihydrido-Ru complex, a variety of Z olefins are accessible under transfer-hydrogenation conditions with formic acid as the hydrogen source in excellent yields and Z/E selectivities.
