A palladium-catalyzed enantioselective intramol. σ-bond cross-exchange between C-I and C-C bonds is realized, providing chiral indanones bearing an alkyl iodide group and an all-carbon quaternary stereocenter, e.g., I. Pd/TADDOL-derived phosphoramidite is found to be an efficient catalytic system for both C-C bond cleavage and alkyl iodide reductive elimination. In addition to aryl iodides, aryl bromides can also be used for this transformation in the presence of KI. D.-functional theory (DFT) calculation studies support the ring-opening of cyclobutanones, e.g., II, occurring through an oxidative addition/reductive elimination process involving PdIV species. In the experiment, the researchers used many compounds, for example, Methyltriphenylphosphonium bromide(cas: 1779-49-3Computed Properties of C19H18BrP)
Methyltriphenylphosphonium bromide(cas: 1779-49-3) is a lipophilic molecule with a cation allowing for it to be used to deliver molecules to specific cell components. Also considered an antineoplastic agent.Computed Properties of C19H18BrP
