Metal-organic frameworks (MOFs) are ac lass of crystalline porousm aterials that have been activelyu sed for several industrial and synthetica pplications.M OFs are spatially and geometrically extrapolatedc oordination polymers with intriguing properties such as tunable porosity and dimensionality.Int erms of their catalytic efficiency,MOFs combine the easy recoverability of heterogeneous catalysts with the increased selectivity of biological catalysts. It is therefore not surprising that alot of work on optimizing MOF catalysts for organic transformationsh as been carriedo ut over the past decade. In this review,recent developments in MOF catalysis are summarized, with special attention being paid to CÀC, CÀN, and CÀOc oupling reactions. The influence of pore size, pore environment, and load on catalytic activity is described. Post-synthetics tabilization techniques and hostguest interactions in caged MOF scaffolds are detailed. Mechanistic aspects pertaining to the use of MOFs in asymmetric heterogeneousc atalysis are highlighted and categorized.

“…As mentiomed in leterature, in the case of noble metals, one of the most widely used methods to stabilize the nanoparticles and control their growth is to use ligands and it is observed that tridentate nitrogen ligands, including terpyridine‐based ligands, increase the dispersion and stability of the metal nanoparticles due to the strong interaction metal‐nitrogen and the formation of two five‐membered metallacycles …”

The palladium nanoparticles were successfully stabilized with an average diameter of 6–7 nm through the coordination of palladium and terpyridine‐based ligands grafted on graphene oxide surface. The graphene oxide supported palladium nanoparticles were thoroughly characterized and applied as an efficient heterogeneous catalyst in carbon–carbon (Suzuki‐Miyaura, Mizoroki‐Heck coupling reactions) and carbon–heteroatom (C‐N and C‐O) bond‐forming reactions. The catalyst was simply recycled from the reaction mixture and was reused consecutive four times with small drop in catalytic activity.

“…Thus, the pyridine maghemite coated-grafted catalyst 62 has been successfully used in the classical Sonogashira reaction with phenylacetylene, the use of chloroarenes needing longer reaction times and reaching lower yields that the related iodoarenes [108]. In addition, another possibility is the stabilization of the palladium by carbine-phospane ligands, as in the case of supported catalyst 63, which allowed to perform the cross-coupling reaction using water as solvent and very low catalyst loading [109].…”

Solid-Supported Palladium Catalysts in Sonogashira Reactions: Recent Developments

Abstract:The Sonogashira cross-coupling reaction is the most frequently employed synthetic procedure for the preparation of arylated alkynes, which are important conjugated compounds with multiple applications. Despite of their rather high price, this reaction is usually catalyzed by palladium species, making the recovery and reuse of the catalyst an interesting topic, mainly for industrial purposes. Easy recycle can be achieved anchoring the palladium catalyst to a separable support. This review shows recent developments in the use of palladium species anchored to different solid supports as recoverable catalysts for Sonogashira cross-coupling reactions.
