Mannitol‐based CO Surrogate for Palladium‐Catalyzed Alkoxycarbonylation

European Journal of Organic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Фев. 6, 2025

Abstract Carbonylative transformation is already been accepted as a powerful toolbox in synthetic chemistry. However, the manipulation of toxic and smell‐less carbon monoxide gas lagged it from wide range applications. Hence developing new efficient CO surrogates become an attractive topic. Herein, we developed novel mannitol‐based surrogate with enhanced loading capacity compared to known organic surrogates. We successfully used palladium‐catalyzed alkoxycarbonylation aryl bromides phenols only 0.5 equivalent required. This newly designed offers additional possibility for further development

Configuration Retention in P-Trifluoromethyl Phosphine Enabled Rh(I)-Catalyzed Decarbonylative Coupling of Carboxylates and Boroxines

As compared with asymmetric catalysis, the memory of chirality provides another promising strategy to introduce chiral centers in light numerous starting materials that can be accessed. Decarboxylative coupling has become an important for C-C or C-X bond formation over decades development its versatility and low cost structural diversity carboxylic acids. However, more general configuration retention this transformation seldom been studied. Here, we report a novel π acceptor-type ligand P-trifluoromethyl phosphine enabled Rh(I)-catalyzed decarbonylative carboxylates boroxines. The α-carbon fully retained chiral, cis-, trans-substrates. Several phosphine-Rh(I) carbonyl complexes were prepared their v(CO) values known complexes, which indicated π-accepting property is reaction.
