Probing Effects of Electron Addition to Polycyclic Conjugated Hydrocarbons Containing Four‐Membered Rings

ChemistryEurope, EarlyView.
Studies of the mono‐ and doubly reduced cyclobutadienoid derivatives with increasing conjugation length reveal that the two‐electron addition does not allow the four‐membered rings to achieve the aromatic square shape, instead resulting in the distorted rectangular or trapezoid geometries, even at the cost of losing aromaticity of the fused benzenoid ...

Pnictogenation‐Driven Exsolution of Size‐Tunable Ru Electrocatalysts in Conductive Matrices to Reinforce Inner‐Sphere‐Mechanism‐Assisted Electronic Coupling

Carbon Energy, EarlyView.
Here, we report an exsolution route to size‐tunable Ru‐metal nanocatalysts embedded in conductive metal pnictogenide matrices via the gas‐phase pnictogenation reaction of Ni2Fe1−xRux‐LDH. The inner‐sphere‐mechanism‐assisted interfacial electronic coupling between exsolved single‐atom nanocatalysts and conductive nickel iron pnictogenide matrices led to

Fused Nitrogen Bridgehead N,O‐Acetals as Versatile Scaffolds: Synthetic Strategies, Mechanism and Applications

Chemistry – A European Journal, EarlyView.
Fused nitrogen‐bridgehead N,O‐acetals receive specific emphasis as pivotal scaffolds due to their significant role in the bioactivity of medicinally relevant molecules. Significant approaches have been reported on their role as key synthetic building blocks/motifs in the construction of complex organic molecules and their utility as chiral auxiliaries ...

Oxidative Folding of a Two‐Chain Protein Having Three Interchain Disulfide Bonds. Synthesis of Bromelain Inhibitor VI Through Native Chain Assembly

Chemistry – A European Journal, EarlyView.
Bromelain inhibitor VI, a two‐chain protein stabilized by three interchain SS bonds and two intrachain SS bonds, was synthesized in an incredibly high isolated yield (53%) just by mixing the two native chains in a buffer solution. This success made a record of oxidative protein folding for the most complicated and difficult one.
