Summary: A series of enantiomerically pure derivatives were successfully synthesized for the first time, with the stereoselective acetylation performed under kinetic resolution conditions using a series of hydrolytic enzymes. The primary alcohols were successfully resolved into enantiomers with moderate to good enantioselectivity, while the secondary alcohols were found to be unreactive in the presence of enzymes. The absolute configurations of the products were determined by X-ray analysis and chemical correlation.

Summary: A new solvent-free synthesis method has been developed for the clean synthesis of a P-carboxy-ethyl derivative with high yield. The resulting phosphabetaine formed crystalline 1D coordination polymers, whose solid state structures were influenced by the anion of the Ag+-salt used in synthesis. The new Ag-based coordination polymers were characterized using various techniques, revealing their loss of polymeric nature upon dissolution in water.

Summary: Temperature can affect the properties of some anticancer drugs, improving their efficiency and selectivity. Gold(I) complexes derived from phosphanes have been found to exhibit antiproliferative effects on colon cancer cells by influencing the intracellular redox state and cell cycle, leading to apoptosis. Furthermore, this cytotoxic effect is enhanced by hyperthermia and polyfluorinated chains.

Summary: The P-31 chemical shift of 1,3,5-triaza-7-phosphaadamantane (PTA) is solely influenced by non-covalent interactions, with a maximum change of 6 ppm due to hydrogen bonding, but over 100 ppm when the phosphorus atom is coordinated to a metal. This difference can be utilized to validate or refute structural models of organometallic transition metal complexes by comparing experimental and DFT calculated values.

Summary: The selective synthesis of a spirobifluorene-iridacyclopentadiene complex was achieved through a methoxyalkenylcarbeneiridium complex. Research on the chemoselectivity of the C?H bond activation revealed that the steric effect of the substituents has a greater influence on the structure of the resulting iridacycle compounds than their electronic character.

Summary: The study investigates the surface charge transfer doping of exfoliated black phosphorus (bP) flakes using copper, with tunneling spectra indicating a gap around copper islands attributed to Coulomb blockade. Line spectroscopic measurements across small copper islands show a short-ranged n-type doping effect of copper on bP. First-principles simulations support these experimental results and demonstrate the electronic decoupling of the topmost bP layer driven by the copper cluster, consistent with the Coulomb blockade interpretation.

Summary: This study investigates the direct chemical reactivity between phosphorus and nitrogen under high-pressure and high-temperature conditions. Two new compounds, α-P3N5 and γ-P3N5, were discovered, and the structural and vibrational changes of γ-P3N5 during compression were analyzed. The detection of α-P3N5 suggests it as an intermediate step in the conversion from phosphorus to γ-P3N5. The findings provide important insights into the chemical reactions between phosphorus and nitrogen.

Summary: Well-defined, bench-stable Mn(I) non-pincer-type complexes were used as catalysts for the selective reduction of CO2 to boryl-protected MeOH in the presence of pinacolborane (HBpin). High yields were achieved under mild reaction conditions without the need for base or additives, using the alkylcarbonyl Mn(I) bis(phosphine) complexes fac-[Mn(CH2CH2CH3)(dippe)(CO)3] [Mn1, dippe = 1,2-bis(diisopropylphosphino)ethane] and [Mn(dippe)(CO)2{(mu-H)2(Bpin)}] (Mn4) as precatalysts. Mechanistic insights were obtained through NMR experiments and monitoring of the catalytic reactions.

Summary: Catalytic hydrogenation of CO2 to formate was achieved using the neutral, halide-free, coordinatively saturated tris(carbonyl) manganese pincer-type complex [Mn(PNP)(CO)(3)] as catalyst, DBU as base, and LiOTf as Lewis acid additive. The reaction conditions were mild (60 bar, 80°C). DFT calculations revealed that the activation of the precatalyst occurred through intermolecular, base-assisted dihydrogen heterolytic splitting.

Summary: In this study, 2D black phosphorus was functionalized with gold nanoparticles through deposition-precipitation reaction, leading to the formation of a heterostructure. Experimental results, supported by DFT calculations, revealed partial charge transfer at the interface of 2D black phosphorus and gold nanoparticles. It was also predicted that functionalization with gold clusters would lower the band gap of phosphorene, with larger effects expected as the cluster size and coverage increase.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
