Special Issue "Solid-Supported Reagents in Palladium-Catalyzed Transformations"
Deadline for manuscript submissions: closed (31 May 2018)
Palladium is arguably the most versatile and most-widely applied metal in catalytic transformations. Thus, palladium-mediated processes have become essential tools in the preparation of natural products, polymers, agrochemicals, pharmaceuticals, industrial commodities, and so on. This far-reaching scope is due to palladium’s ability to participate in catalytic transformations, as well as its high functional group tolerance. Palladium can be used to conduct uncountable transformations with organic molecules. In fact, there are many well-known name reactions that feature this metal, such as the Heck, Suzuki, Stille, Sonogashira and Buchwald-Hartwig cross-couplings, the Wacker process or the Tsuji-Trost allylation. In addition, palladium catalysis also enables hydrogenation, hydrogenolysis, carbonylation, oxidation, carbon-carbon and carbon-heteroatom bond formation, or cycloisomerization reactions. Domino processes, where multiple palladium-promoted transformations are carried out in a single operation, are also a powerful application of palladium catalysis. Palladium-catalyzed procedures often take place under mild conditions, affording high yields, with excellent levels of selectivity. All these processes mainly take place under homogeneous conditions, something that represents a serious drawback for large-scale applications, considering the problem associated with the recovery of the often-expensive palladium catalyst after product formation.
Immobilization of the palladium catalyst on a solid and insoluble support can drive to advantages related to its easier isolation and recycling compared to the cases of soluble counterparts, or its use in continuous flow chemistry. In the last years, many examples have been reported on the use of palladium species, such as complexes or nanoparticles, anchored to a solid support as recyclable catalysts. Thus, numerous solid supports have been employed for anchoring the palladium species, such as polymers, silica-related materials, metal oxides, carbon-based structures, metal organic frameworks, etc. However, despite these developments, plenty of work is still ahead to achieve supported catalytic palladium systems successfully applicable to all reactions suitable to being carried out under homogeneous conditions above mentioned, paying special attention to aspects, such as their high reactivity and recyclability.
This Special Issue of Catalysts aims to provide a diverse overview of the latest developments in the preparation of solid-supported palladium species and their use as catalysts in all these interesting chemical transformations.Prof. Dr. Rafael Chinchilla
