O–CN Bond Cleavage of Cyanates by a Transition-Metal Complex
, 2016 O–CN bond cleavage of cyanates (ROCN) has been achieved at room temperature in the reaction of ROCN with a methyl Fe, Mo, or W complex. A mechanistic investigation involving DFT calculations revealed that silyl migration from Mo to the CN nitrogen gave ...

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

A modular catalytic approach towards pyridine and quinolone synthesis [PDF]
, 2013 N-Containing heterocycles such as substituted pyridines and 2-quinolones are commonly found in drugs and agrochemicals; however, classical methods towards their synthesis often lead to limited substitution patterns.

Mechanistic Understanding of Nickel Catalyzed Urea Oxidation Reaction to Cyanate and Nitrite
Exploration, EarlyView.The urea oxidation reaction (UOR) is a promising alternative to oxygen evolution reaction (OER) for energy efficient hydrogen production, yet its reaction mechanism remains controversial because many proposed pathways have not been directly correlated with experimentally verified products and intermediates.

Polarizability anisotropy and spatial structures of aryl cyanates
, 2020 1. The polarizability parameters of the cyanate group have been determined. 2. Phenyl cyanate and p-methoxyphenyl cyanate possess a planar, and p-chloro-p-bromo-, and nitrophenyl cyanates possess a nonplanar, conformation in solutions.

The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions
ChemistryEuropeIn contrast to the simple and straightforward generation of pyridinium cations, the P‐alkylation of the heavier homolog λ3σ2‐phosphinines is more challenging due to their weak nucleophilicity, as demonstrated only by a handful of examples. The previously

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites
Journal of Polymer Science, EarlyView.In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

The Journal of Physiology, EarlyView.Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained
