Devarajan, Nainamalai published the artcileCopper-catalyzed oxidative coupling of arylboronic acids with aryl carboxylic acids: Cu3(BTC)2 MOF as a sustainable catalyst to access aryl esters, Application In Synthesis of 197958-29-5, the publication is Organic Chemistry Frontiers (2018), 5(15), 2322-2331, database is CAplus.
A convenient and sustainable method was demonstrated for the oxidative coupling of arylboronic acids with aryl carboxylic acids via C-O cross-coupling reaction catalyzed by the unsaturated coordination sites of copper present in the Cu3(BTC)2 MOF. Cu3(BTC)2 was employed in a MOF-based catalysis reaction with high efficiency and high chemoselectivity without the use of any external oxidants, ligands or additives. The present methodol. avoided stoichiometric reagents and special reaction conditions and showed excellent functional group tolerance with decent to excellent yields of aryl esters R1C(O)OR2 [R1 = Ph, 4-ClC6H4, 2-naphthyl, etc.; R2 = Me, 3-MeOC6H4, 4-O2NC6H4, etc.]. The catalyst was found to exhibit high stability and reusability, without loss in activity even after several cycles, which was evident from the FT-IR, PXRD and SEM characterizations of the reused catalyst.
