A metal carbene one is named for Grubbs, while an organopalladium one is used in the Heck reaction.
One of these reacts with carbon monoxide to form a less reactive version of Vaska's complex; that one, named for Wilkinson, is much less effective that a similar iridium-based one named for Crabtree. The turnover number is one measure of their efficiency, and lead compounds are often used to "poison" them. A metal carbene one is named for Grubbs, while an organopalladium one is used in the Heck reaction. One of these composed of an aluminum-nickel alloy is named for Raney, while terminal 1-alkenes are polymerized using a titanium- based one named for Ziegler and Natta. For 10 points, identify these substances which increase the speed of chemical reactions without being consumed themselves.
