Carboaminocarbonylation
WebThe transition-metal-catalyzed “cut and sew” transformation has recently emerged as a useful strategy for preparing complex molecular structures. After oxidative addition of a transition metal into a carbon–carbon bond, the resulting two carbon termini can be both functionalized in one step via a following migratory insertion and reductive elimination … WebAug 7, 2024 · A rhodium-catalyzed direct insertion of ethylene into a relatively unstrained carbon–carbon bond in 1-indanones is reported, which provides a two-carbon ring expansion strategy for preparing seven-membered cyclic ketones. As many 1-indanones are commercially available and ethylene is inexpensive, this strategy simplifies synthesis of …
