The Eisenberg group's Naz
The Eisenberg group's Nazarov-Michael sequence used a catalyst employing this element for both steps, and the dodecacarbonyl of this element is used to prepare catalysts for the water gas shift reaction. George Morris and his mentor discovered a square planar catalyst with this element for alkene hydrogenation that is far faster than Wilkinson's; that compound is called Crabtree's catalyst. Another catalyst of this element was replaced when a rhodium catalyst was used instead to carbonylate methanol - that reaction is the Cativa Process. This element is the central component of Vaska's complex, and it was the first one to be shown to display the Mossbauer effect. The second-densest element after osmium, FTP, name this element shown to exist near the K-T boundary in support of the Alvarez Hypothesis, and is named for its rainbow-like color.
