Regio- and Stereoselective Cyanotriflation of Alkynes Using Aryl(cyano)iodonium Triflates

A novel, mild, and versatile approach for regioselective <i>syn</i>-addition of both the CN and OTf groups of aryl­(cyano)­iodonium triflates to alkynes is described. The reaction uses Fe-catalysis and can be conducted in gram scale. Products of the vicinal cyanotriflation can be stereospecifically readily further functionalized, rendering the method highly valuable

Regio- and Stereoselective Radical Perfluoro­alkyltriflation of Alkynes Using Phenyl­(perfluoro­alkyl)­iodonium Triflates

A method for regio- and stereoselective anti-addition of the perfluoroalkyl and the triflate group of phenyl­(perfluoro­alkyl)­iodonium triflates to alkynes is presented. The radical reaction uses cheap CuCl as a smart initiator and can be conducted in gram scale. The perfluoroalkyltriflated products are readily further functionalized, rendering this transformation valuable

Galvanostatic Electrodeposition of Durable IrO_<i>x</i> Films on Low-Iridium-Supported Titanium for an Acidic Oxygen Evolution Reaction

Ensuring or even optimizing the activity and stability of iridium oxide-coated titanium anodes while reducing the amount of iridium is still practically significant. In this work, IrOx-Ti electrodes are prepared by galvanostatic deposition at different deposition current densities and times. The iridium loading level, morphology, microstructure, and element composition distribution of these obtained electrodes are characterized, and their cyclic voltammetry and accelerated life tests were carried out in 0.5 M H2SO4 to investigate their electrochemical performance for the acidic oxygen evolution reaction (OER). For a better understanding of the anodic electrodeposition mechanism, a competing mechanistic hypothesis was proposed to describe the reactions and their relationship involved in this process. The results show that the IrOx electrodes electrodeposited at 0.1 mA cm–2 exhibited a superior performance for the OER in terms of stability. Especially, the electrode electrodeposited for 5 h (0.1 mA cm–2) demonstrated a long-term durability for 73.14 h (equivalent to at least 14,642 h, i.e., 610 days, in actual lifetime) with 1.0 mg cm–2 iridium loading. Simultaneously, a mathematical model was used to fit the relationship between accelerated lifetime and deposition current and iridium loading. This research provides some valuable insights into how to optimally use Ir as an OER electrocatalyst

siRNA–targeting of VarTEs and the effect on proximal gene expression.

<p>(a) Upper panel depicts siRNA-targeting of variable and invariable regions of VarTEs defined between Col-0 and Bur-0 or C24. Lower panel shows abundance of Col-0 siRNA in siRNA+ InvTEs (red) and siRNA+ VarTEs (yellow) between Col-0 and Bur-0 or C24. Within siRNA+ VarTEs, the abundance of Col-0 siRNA was compared between invariable (cyan) and variable regions (navy). MWU [InvTE/VarTE] p<2×10⁻¹⁶ for Col-0 versus Bur-0/C24. MWU [variable/invariable regions of VarTEs] p[Col-0/Bur-0] = 1×10⁻⁵, p[Col-0/C24]<2×10⁻¹⁶ (b) VarTE+ genes were divided into subgroups based on whether the closest proximal TE was siRNA− (cyan), InvsiRNA+ (dark gray) or VarsiRNA+ (light gray). The average expression level of each gene group is shown. MWU [siRNA− VarTE+/InvsiRNA+ VarTE+] p[Col-0/C24] = 0.01, p[Col-0/Bur-0] = 0.01; MWU [siRNA− VarTE+/VarsiRNA+ VarTE+] p[Col-0/C24] = 9×10⁻⁵, p[Col-0/Bur-0] = 0.003; MWU [VarsiRNA+ VarTE+/InvsiRNA VarTE+] p[Col-0/C24] = 0.01, p[Col-0/Bur-0] = 0.04; * = p<0.05, ** = p<0.01.

A Clear Insight into the Distinguishing CO₂ Capture by Two Isostructural Dy^III–Carboxylate Coordination Frameworks

Two isostructural <i><b>the</b></i>-type Dy^III coordination networks were successfully constructed based on a pair of analogous tribenzoate bridging ligands with phenyl and triazinyl central spacers. Notably, the active triazinyl group can obviously enhance the capability and selectivity of CO₂ sorption for the porous framework

Relationship of TE siRNA–targeting to distance from genes and its effect on gene expression in Col-0.

<p>(a) Average distance of siRNA− (red) and siRNA+ (yellow) proximal TEs to the nearest gene. For siRNA+ proximal TEs, distance to the closest gene is compared between msiRNA+ TEs (cyan) and usiRNA+ TEs (navy). MWU [siRNA+/siRNA−] p<2.2×10⁻¹⁶ for Col-0, Bur-0 and C24. MWU [msiRNA/usiRNA] p[Col-0]<2×10⁻¹⁶, p[Bur-0] = 6×10⁻¹³ and p[C24] = 2×10⁻⁶. (b) Average expression level of genes when neighboring TEs are siRNA− (red) or siRNA+ (yellow). For siRNA+ TEs, average gene expression levels are given for when the nearest TE is distal (greater than 2 kb from gene; dark gray) or proximal (within 2 kb; light gray). For genes with proximal siRNA+ TEs, expression levels were further compared between msiRNA+ TEs (cyan) and usiRNA+ TEs (navy).
