Kim, Dong Sun;Lee, Hong Geun research published ã?Formation of the Tertiary Sulfonamide C(sp³)-N Bond Using Alkyl Boronic Ester via Intramolecular and Intermolecular Copper-Catalyzed Oxidative Cross-Couplingã? the research content is summarized as follows. A synthetic strategy for the formation of C(sp³)-N bonds, particularly through a Cu-catalyzed oxidative cross-coupling, is rare. Herein, the authors report a novel synthetic approach for the preparation of tertiary sulfonamides via Cu-catalyzed intra- and intermol. oxidative C(sp³)-N cross-coupling reactions. This method allows the use of the readily available C(sp³)-based pinacol boronate as a substrate and the tolerance of a wide range of functional groups under mild reaction conditions. The success of this strategy relies on the unprecedented additive effects of silanol and NaIO₄.

Kim, Hyunyong;Kim, Hyunseok;Kim, Kimoon;Lee, Eunsung research published ã?Construction of Stable Metal-Organic Framework Platforms Embedding N-Heterocyclic Carbene Metal Complexes for Selective Catalysisã? the research content is summarized as follows. We report a bottom-up approach to immobilize catalysts into MOFs, including copper halides and gold chloride in a predictable manner. Interestingly, the structures of MOFs bearing NHC metal complexes maintained a similar 4-fold interpenetrated cube. They exhibited exceptionally high porosity despite the interpenetrated structure and showed good stability in various solvents. Moreover, these MOFs possess high size activity depending on the size of the substrates in various reactions, compared to homogeneous catalysis. Also, the high catalytic activity of MOFs can be preserved 4 times without significant loss of crystallinity. Incorporation of the various metal complexes into MOFs allows for the preparation of functional MOFs for practical applications.

Koller, Sebastian;Klein, Philippe;Reinhardt, Katja;Ochmann, Lukas;Seitz, Antonia;Jandl, Christian;Pothig, Alexander;Hintermann, Lukas research published ã?New Access Routes to Privileged and Chiral Ligands for Transition-Metal Catalyzed Hydrogen Autotransfer (Borrowing Hydrogen), Dehydrogenative Condensation, and Alkene Isomerization Reactionsã? the research content is summarized as follows. A group of transition-metal catalyzed hydrogen moving reactions, encompassing hydrogen autotransfer (HAT; also called borrowing hydrogen, BH), dehydrogenative condensation (DHC) and alkene isomerization, displays high atom economy and relies on widely available starting materials. Such reactions have considerable potential for clean reaction design and application in sustainable synthesis. With the aim to develop and study synthetic applications of the title reactions, authors have set up synthetic access routes to a toolbox of structurally varied ligands for and pincer complexes of some transition metals (cobalt, ruthenium, iridium) that are well established for the title reactions. Ligand target structures, for which often improved syntheses have been found, encompass 6,6′-dihydroxy-2,2′-bipyridine, 2(3-hydroxyphenyl)pyridines (as backbones for PCN pincers), 2(6-methylpyridine-2-yl)pyridines (as backbones for PNN pincers) and 2(3-tolyl)pyridines (as backbones for PCN pincers). To support research towards asym. versions of the title reactions, they have prepared asym. modified versions of well-established catalysts, including chiral, enantiopure versions of Milstein’s PNN-ruthenium pincer, Kempe’s triazinyl-diaminophosphanyl PNP-iridium- or -cobalt pincers, Huang’s PCN-iridium pincers, and Grotjahn’s alkene zipper complex. The strategy applied to ‘chiral switching’ relied on replacing sym. dialkylphosphine donor-groups by dimenthylphosphine or aryl(menthyl)phosphine donor units. The resulting ligands or complexes have been structurally characterized, and the catalytic potential of the catalysts has been established in exploratory model reactions (transfer hydrogenation; diol to lactone dehydrogenative condensation; alkene isomerization). Several model reactions have been designed which will allow to study asym. catalytic hydrogen moving reactions.

Kang, Jisu;Zaen, Rena;Lee, Ji Hye;Hwang, Hyonseok;Park, Ki-Min;Kim, Seung Chan;Lee, Jun Yeob;Kang, Youngjin research published ã?Effect of ancillary ligand on the photoluminescent and electroluminescent properties of blue Ir(III) complexes bearing main bipyridine ligandã? the research content is summarized as follows. Homoleptic and heteroleptic cyclometalated blue iridium(III) complexes, namely, 1 and 2, incorporating 2â?6â?dimethoxy-5-trimethylsilyl-2,3â?bipyridine (OMe₂py-TMSpy) as the main ligand and acetylacetonate (acac) as the ancillary ligand, are developed for the comparison of their structure, photophys. properties, and electroluminescent characteristics. Both 1 and 2 exhibit distorted octahedral geometries around the iridium center, and the aspect ratios are 1.0 for 1 and 0.76 for 2, resp. The interat. contacts involving hydrogen bond interactions (HÂ·Â·Â·N/O) in 1 are greater than those in 2, based on Hirshfeld surface anal. TD-DFT calculations reveal that the electronic transition for 1 may be attributed to intra-ligand charge transfer (ILCT, Ï_bpy-Ï*_bpy) mixed with metal-to-ligand charge transfer (MLCT, Ir_d-Ï*_bpy), while for 2, it is attributed to the combination of ILCT/MLCT and addnl. ligand-to-ligand charge transfer (LLCT, Ï_acac-Ï*_bpy). Owing to the introduction of the ancillary ligand, the emission of complex 2 is red-shifted by only 6 nm compared to complex 1. However, the photoluminescent quantum efficiency of 2 is higher than that of 1 owing to the high radiative decay rate. Furthermore, phosphorescent organic light-emitting diodes (PhOLEDs) based on 2 achieve a high external quantum efficiency of 26.7%, which is one of the highest performances observed among reported blue PhOLEDs.

Kawazu, Ryohei;Torigoe, Takeru;Kuninobu, Yoichiro research published ã?Iridium-Catalyzed C(sp³)-H Borylation Using Silyl-Bipyridine Pincer Ligandsã? the research content is summarized as follows. New ligands for the iridium-catalyzed C(sp³)-H borylation of aliphatic compounds were established. In sharp contrast to 6-methyl-2,2′-bipyridine and 6-isobutyl-2,2′-bipyridine, 2,2′-bipyridine and 1,10-phenanthroline derivatives bearing a hydrosilylmethyl group (which would give a thermally stable NNSi pincer complex) served as suitable ligands for the reaction. Among them, a phenanthroline-based NNSi pincer ligand was an excellent ligand, and various aliphatic compounds were efficiently converted to the corresponding borylated products using the Ir/NNSi pincer catalyst system. The NNSi pincer ligand showed unique selectivity and enabled the iridium-catalyzed C(sp³)-H borylation using pinacolborane [H-B(pin)] instead of B₂(pin)₂. The formation of an iridium complex bearing a quinoline-based NNSi pincer ligand from [IrCl(cod)]₂ was observed, and the catalytic activity of the complex was demonstrated.
