המילה המקורית מן השתיים היא המילה קַבְקַב. מקורה במילה הערבית قَبْقَاب (קַבְּקַאבּ), המשמשת במשמעות נעל עץ, כנראה בשל קול הנקישות שמשמיעה נעל זו בעת ההליכה בה.[1] בעברית של ראשית המאה העשרים אימצו את המילה הערבית אגב סיגולה לעברית – בבי"תין רפות – באותה המשמעות: וראיתי את חמוקי שוקיה ואת רגליה העגולות בהתנענען על קבקבים של עץ.

Oxidative dehydrogenation of ethane (ODE) is limited by the facile deep oxidation and potential safety hazard. Herein, electrochemical ODE reaction is incorporated into the anode of a solid oxide electrolysis cell, utilizing the oxygen species generated at anode to catalytically convert ethane, which can avoid deep oxidation and reaction unsafety. By infiltrating g‐Al 2 O 3 onto the surface of La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3‐ δ ‐Sm 0.2 Ce 0.8 O 2‐ δ (LSCF‐SDC) anode, the ethylene...

The stability of metal nanocatalysts for electrocatalytic CO2 reduction is of key importance for any practical application. We report the use of two polymeric N‐heretocyclic carbenes (NHC) (polydentate and monodentate) to stabilize metal nanocatalysts (Au and Pd) for efficient CO2 electroreduction. Compared with other conventional ligands including thiols and amines, metal‐carbene bonds that are stable under reductive potentials prevent the nanoclustering of nanoparticles. In particular, Au nanocatalysts...

Highly enantioselective rhodium‐catalyzed addition of arylboroxines to N‐unprotected ketimines are realized for the first time by employing chiral BIBOP‐type ligands with the Rh loading as low as 1 mol %. A range of chiral α‐trifluoromethyl‐α,α‐diaryl α‐tertiary amines or 3‐amino‐3‐aryloxindoles were formed in excellent ee’s and yields with the employment of WingPhos or PFBO‐BIBOP as the ligand. The method has enabled an efficient enantioselective synthesis of cipargamin.

Chemical transformations that install heteroatoms into C–H bonds are of significant interest because they streamline the construction of value‐added small molecules. Direct C−H oxyfunctionalization, or the one step conversion of a C–H bond to a C–O bond, could be a highly enabling transformation due to the prevalence of the resulting enantioenriched alcohols in pharmaceuticals and natural products,. Here we report a single‐flask photoredox/enzymatic process for direct C–H hydroxylation that proceeds...

The hydroxide trihydrate anion was generated for the first time and structurally characterized thanks to the use of a weakly coordinating phosphazenium counterion. As B. Hoge et al. describe in their Communication (DOI: https://doi.org/10.1002/anie.20190858910.1002/anie.201908589), the space‐filling phosphazenium cation represents an impregnable castle wall in protecting and stabilizing this rare anion. Under vacuum the salt decomposes like a fragile aqueous “hydroxide soap bubble”.

Low‐overpotential selective eCO2RR: A formate efficiency of 94.3 % at a low overpotential of 450 mV was achieved by an amorphous Ag‐Bi‐S‐O decorated Bi0 nanocatalyst derived from bimetal‐S‐O composite Ag0.95BiS0.75O3.1. The performance arises from the role of S in accelerating the dissociation of H2O and the higher local pH resulted from the existence of Ag. Abstract Bimetal‐S‐O composites have been rarely researched in electrochemical reduction of CO2. Now, an amorphous Ag‐Bi‐S‐O decorated...

A de novo designed...

In the evolution of metal−organic frameworks (MOFs) for carbon capture, a lasting challenge is to strike a balance between high uptake capacity/selectivity and low energy cost for regeneration. Meanwhile, these man‐made materials have to survive from practical demands such as stability under harsh conditions and feasibility of scale‐up synthesis. Reported here is a new MOF, Zn(imPim) (aka. MAF‐stu‐1), with an imidazole derivative ligand, featuring binding pockets that can accommodate CO 2 molecules...
