Koller, Sebastian;Klein, Philippe;Reinhardt, Katja;Ochmann, Lukas;Seitz, Antonia;Jandl, Christian;Pothig, Alexander;Hintermann, Lukas research published 《 New Access Routes to Privileged and Chiral Ligands for Transition-Metal Catalyzed Hydrogen Autotransfer (Borrowing Hydrogen), Dehydrogenative Condensation, and Alkene Isomerization Reactions》, 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.

Komarova, Anastasia O.;Dick, Graham R.;Luterbacher, Jeremy S. research published 《 Diformylxylose as a new polar aprotic solvent produced from renewable biomass》, the research content is summarized as follows. Demand for sustainable polar aprotic solvents is increasing due to their unique solubilizing properties and the toxicity of conventional analogs, which are facing pressure from extensive safety legislation. Polar aprotic solvents are particularly difficult to produce renewably because polar mols. that lack hydroxyl groups are rarely found in abundance in the natural world. Here, we explore the use of diformylxylose (DFX), a xylose-derived mol. that can be produced in a single step from lignocellulosic biomass, as a novel polar aprotic bio-based solvent. We notably demonstrate that diformylxylose shows a similar performance to conventional polar aprotic solvents (DMF, NMP, DMSO) in alkylation, cross-coupling (Heck), and hydrogenation reactions. We also demonstrate its straightforward production from com. xylose and show that it is non-mutagenic, according to the Ames test. Renewable DFX appears to be a greener alternative to common polar aprotic solvents that are considered problematic for industry.

A series of imidazolinium salts, their six-, seven- and eight-membered homologues, and the related formamidinium salts were prepared, and their pK_a values were determined in DMSO at 25°C using the bracketing indicator method. The effect of each type of structural variation on the acidity of each salt was considered, particularly noting the importance of ring size and the effect of the steric and electronic nature of the N-aryl substituents. The effect of a cyclic structure was also probed through comparing the cyclic systems with the corresponding formamidinium salts, noting the importance of conformational flexibility in the latter cases. Along with allowing choice of appropriate bases for deprotonation of these species, it is anticipated that the data presented will aid in the understanding of the nucleophilicity, and potentially catalytic efficacy, of the corresponding carbenes.

Bridging polymer design with catalyst surface science is a promising direction for tuning and optimizing electrochem. reactors that could impact long-term goals in energy and sustainability. Particularly, the interaction between inorganic catalyst surfaces and organic-based ionomers provides an avenue to both steer reaction selectivity and promote activity. Here, we studied the role of imidazolium-based ionomers for electrocatalytic CO₂ reduction to CO (CO₂R) on Ag surfaces and found that they produce no effect on CO₂R activity yet strongly promote the competing hydrogen evolution reaction (HER). By examining the dependence of HER and CO₂R rates on concentrations of CO₂ and HCO₃^–, we developed a kinetic model that attributes HER promotion to intrinsic promotion of HCO₃^– reduction by imidazolium ionomers. We also show that varying the ionomer structure by changing substituents on the imidazolium ring modulates the HER promotion. This ionomer-structure dependence was analyzed via Taft steric parameters and d. functional theory calculations, which suggest that steric bulk from functionalities on the imidazolium ring reduces access of the ionomer to both HCO₃^– and the Ag surface, thus limiting the promotional effect. Our results help develop design rules for ionomer-catalyst interactions in CO₂R and motivate further work into precisely uncovering the interplay between primary and secondary coordination in determining electrocatalytic behavior.

Koyama, Katsumasa;Anno, Takatoshi;Kawasaki, Fumiko;Nishino, Ken;Kawamoto, Hirofumi;Kaneto, Hideaki;Tomoda, Koichi research published 《 Edematous wall thickening of the gallbladder induced by hyperthyroidism: A case report.》, the research content is summarized as follows. RATIONALE: Hyperthyroidism, such as Basedow disease, causes fluid retention, although the common cause is volume overload due to congestive heart failure. In addition, hyperthyroidism and Basedow disease are known to cause pulmonary hypertension. Edematous thickening of the gallbladder wall is caused by venous blood congestion. The feature of edematous wall thickening of the gallbladder on abdominal computed tomography (CT) is subserosal edema and is often accompanied by a periportal collar sign. PATIENT CONCERNS: A 30-year-old woman was referred to our hospital because of liver dysfunction, edematous gallbladder wall thickening, and fluid retention. In addition, the patient developed hyperthyroidism and heart failure. Enhanced abdominal CT revealed edematous wall thickening of the gallbladder and a periportal collar sign. DIAGNOSIS: We suspected that fluid retention and congestion were caused by hyperthyroidism and Basedow disease. INTERVENTIONS: On admission, we started thiamazole therapy for Basedow disease, and her thyroid hormone levels normalized. OUTCOMES: Abdominal CT revealed disappearance of edematous wall thickening of the gallbladder, which was likely associated with an improvement in thyroid function. The patient was discharged 10 days after admission. LESSONS: We encountered a case of hyperthyroidism and Basedow disease accompanied by edematous wall thickening of the gallbladder and various fluid retentions as the first symptoms. Such edematous wall thickening of the gallbladder and various fluid retentions were reduced, together with the improvement of hyperthyroidism.
