Metal–Organic Frameworks with Phosphonate Monoester Linkers for Catalytic C(sp²)–H Borylation of Alkenes

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 3, 2025

An isoreticular metal-organic framework (MOF) series was constructed from nickel or cobalt nodes, phosphonate monoester, and bipyridine linkers. The cobalt-containing MOFs were found to catalyze the dehydrogenative C-H borylation of alkenes under mild conditions. This process selectively generates vinyl boronate without formation alkyl byproducts is insensitive air, enabling large-scale preparation target products with isolated yields over 80%.

Abstract A functionalized heterogeneous Cu‐based metal‐organic framework (Cu‐2D‐MOF) was synthesized through the reaction of Cu(NO 3 ) 2 ⋅ 3H O with 2,3,5,6‐tetrafluoroterephthalic acid and 4,4′‐bipyridine. The material underwent comprehensive characterization using various techniques, including FT‐IR spectroscopy, N physical adsorption, scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS). Subsequently, catalytic performance Cu‐2D‐MOFs assessed in hydrophosphorylation aerobic oxidative dehydrogenative coupling reactions involving alkynes P−H bonds. catalyst demonstrated remarkable activity both transformations, effectively yielding a wide variety ( E )‐alkenyl‐phosphoryl alkynyl‐phosphoryl compounds, respectively. Notably, incorporation this MOF facilitated phosphorylation to proceed seamlessly, eliminating necessity for supplementary small molecular organic ligands. Furthermore, ease recovery recyclability simple process. Employing systematic approach sequential control experiments, we have delineated potential transformation pathway consequently hypothesized probable mechanism observed transformation.
