Constraint of a ruthenium-carbon triple bond to a five-membered ring
Science Advances, 2018 The first incorporation of a second-row transition metal carbyne unit into a ring is realized by virtue of aromaticity. The incorporation of a metal-carbon triple bond into a ring system is challenging because of the linear nature of triple bonds.
