These structures were converted into energetically unfavorable bis(organyl)metal complexes using a rhodium(I) (“rhodium-one”) catalyst by Suggs and Jun. A common reaction that forms these structures may replace a substituent with a “dummy ligand” such as a cyanide group to prevent an organocopper byproduct. Alkyl halides are reacted with two equivalents of sodium metal to form these structures in the Wurtz reaction. Reactions that form these structures follow cycles of oxidative addition, transmetallation, and reductive elimination and often use a palladium catalyst, such as in the Heck and Suzuki reactions. These structures can be formed using compounds of the form RMgX, such as the formation of a tertiary alcohol from a ketone (-5[1])in the Grignard reaction. For 10 points, name these bonds that form the backbone of organic molecules. ■END■ (10[1])
