TL;DR: A ruthenium(II)-NNC pincer complex containing an unsymmetrical tridentate pyrazolyl-pyridyl-tolyl ligand exhibited excellent catalytic activity for the transfer hydrogenation of ketones in 2-propanol at reflux, and for the Oppenauer-type dehydrogenative oxidation of alcohols in acetone atReflux.
Abstract: A ruthenium(II)-NNC pincer complex containing an unsymmetrical tridentate pyrazolyl-pyridyl-tolyl ligand was synthesized and structually characterized. This complex exhibited excellent catalytic activity for the transfer hydrogenation of ketones in 2-propanol at reflux, and for the Oppenauer-type dehydrogenative oxidation of alcohols in acetone at reflux (see scheme).

TL;DR: Progress in their use as catalysts for (de)hydrogenation and transfer ( de)Hydrogenation reactions during the last four years is covered in this Minireview.
Abstract: Pincer complexes are becoming increasingly important for organometallic chemistry and organic synthesis. Since numerous applications for such catalysts have been developed in recent decades, this Minireview covers progress in their use as catalysts for (de)hydrogenation and transfer (de)hydrogenation reactions during the last four years. Aside from noble-metal-based pincer complexes, the corresponding base metal complexes are also highlighted and their applications summarized.

TL;DR: This perspective highlights recent, important examples of non-symmetric pincer ligands, which feature aryl or pyridine backbones, and the synthesis and use of subsequent complexes in catalytic transformations, and discusses the future potential of this type of ligand system.
Abstract: Pincer ligands have become ubiquitous in organometallic chemistry and homogeneous catalysis. Recently, new varieties of pincer ligands with non-symmetrical backbones and/or ligating groups have been reported and their application in transition metal complexes has been exploited in a variety of catalytic transformations. This non-symmetric approach vastly increases the structural and electronic diversity of this class of ligand. This approach has proven beneficial in a variety of ways, such as the use of a single weakly coordinating moiety, which can dissociate and thereby create a vacant coordination site to increase the catalyst activity. Additionally, this provides further access to chiral ligands and complexes for asymmetric induction. This perspective highlights recent, important examples of non-symmetric pincer ligands, which feature aryl or pyridine backbones, and the synthesis and use of subsequent complexes in catalytic transformations, and discusses the future potential of this type of ligand system.

TL;DR: In this article, the main processes for asymmetric transfer hydrogenation of ketones from 2008 up to today are considered, paying special attention to functionalized substrates, tandem reactions, processes under nonconventional conditions, supported catalysts, dynamic kinetic resolutions, the use of water as a green solvent, theoretical and experimental studies on reaction mechanisms, enzymatic processes, and finally applications to the total synthesis of biologically active organic molecules.
Abstract: In this review, we consider the main processes for the asymmetric transfer hydrogenation of ketones from 2008 up today. The most effective organometallic compounds (derived from Ru, Rh, Ir, Fe, Os, Ni, Co, and Re) and chiral ligands (derived from amino alcohols, diamines, sulfur- and phosphorus-containing compounds, as well as heterocyclic systems) will be shown paying special attention to functionalized substrates, tandem reactions, processes under non-conventional conditions, supported catalysts, dynamic kinetic resolutions, the use of water as a green solvent, theoretical and experimental studies on reaction mechanisms, enzymatic processes, and finally applications to the total synthesis of biologically active organic molecules.
