Summary of "Metal-Organic Frameworks as Catalysts for Organic Synthesis: A Critical Perspective."

Recent advances in organic chemistry and materials chemistry have enabled the porosity of new materials to be accurately controlled on the nanometer scale. In this context, metal-organic frameworks (MOFs) have rapidly become one of the most attractive classes of solid supports currently under investigation in heterogeneous catalysis. Their unprecedented degree of tunability gives MOFs the chance to succeed where others have failed. The last decade has witnessed an exponential growth in the complexity of new structures. MOFs with a variety of topologies and pore sizes show excellent stability across wide ranges of pH and temperature. Even the controlled insertion of defects, to alter the MOF's properties in a predictable manner, has become commonplace. However, research on catalysis with MOFs has been sluggish in catching up with modern trends in organic chemistry. Relevant issues such as enantioselective processes, C-H activation, or olefin metathesis are still rarely discussed. In this perspective, we highlight meritorious examples that tackle important issues from contemporary organic synthesis, and that provide a fair comparison with existing catalysts. Some of these MOF catalysts already outcompete state-of-the-art homogeneous solutions. For others, improvements may still be required, but they have merit in aiming for the bigger challenge. Furthermore, we also identify some important areas where MOFs are likely to make a difference, by ad-dressing currently unmet needs in catalysis instead of trying to outcompete homogeneous catalysts in areas where they excel. Finally, we strongly advocate for rational design of MOF catalysts, founded on a deep mechanistic understanding of the events taking place inside the pore.

Medical and Biotech [MESH] Definitions

Supramolecular networks that consist of ordered arrangements of organic electron donor linkers (usually ditopic or polytopic organic carboxylates) and metal cations. They can have an extremely high surface area and adjustable pore size that allows for the insertion of other molecules capable of various functions such as catalysis, capture of carbon dioxide, and drug delivery.

Organic compounds that have a relatively high VAPOR PRESSURE at room temperature.

Inorganic derivatives of ammonia by substitution of one or more hydrogen atoms with chlorine atoms or organic compounds with the general formulas R2NCl and RNCl2 (where R is an organic group).

Compounds derived from organic or inorganic acids in which at least one hydroxyl group is replaced by an –O-alkyl or other organic group. They can be represented by the structure formula RCOOR’ and are usually formed by the reaction between an acid and an alcohol with elimination of water.

Organic compounds containing the nitroso (-N=O) group attached to an organic moiety.
