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.
