Recent advances in the catalytic oxidation of alkene and alkane substrates using immobilized manganese complexes with nitrogen containing ligands [PDF]

, 2019
In recent years, many supported manganese catalysts for the oxidative transformations of hydrocarbons by various terminal oxidants have been designed and tested. A vast range of inorganic (e.g. silica, carbon, zeolites), organic (e.g.

N–O Dual Functional Group Transposition via Energy Transfer Photocatalysis

Advanced Science, EarlyView.
N–O dual functional group transposition (dFGT) enabled by the photocatalytic energy transfer (EnT) has been developed. This methodology is applicable to both activated and unactivated alkyl derivatives for dFGT, and it also successfully extended to N–N dFGT, demonstrating its general applicability.

Visible‐Light‐Mediated Lewis Acid‐Catalyzed Diradical Hydrogen Atom Transfer Reaction of Enamides

Advanced Science, EarlyView.
The Lewis acid catalysis was crucial for the success of the DHAT reaction of enamides by lowering the energy of the triplet excited state and modulating the reactivity of the formed diradical intermediate in a carbon‐to‐carbon 1,5‐DHAT and consequent cyclization that allows the functionalization of C(sp3)−H bonds to construct a variety of novel β ...

Hydrogenation of non-polar Fraction of Bio-oil from Co-pyrolysis of Corn Cobs and Polypropylene for Bio-diesel Production

E3S Web of Conferences, 2018
Bio-diesel was synthesized by hydrogenating the non-polar fraction of the bio-oil produced from the co-pyrolysis between corncobs and polypropylene. Co-pyrolysis of corn cobs and polypropylene was conducted in a stirred tank reactor at heating rate of 5 ...

Synergistic p53 Pathway Activation Through Sono‐Gene Therapy Induced by Ultrasound‐Triggered Theranostic Mesoporous Nanoparticles

Advanced Science, EarlyView.
Schematic representation of ultrasound‐mediated ICG/siCD24@MSN‐LCD from nanostructure to synergistic sono‐gene therapy. This nanoplatform targets ASGPR via the LCD shell, which dissociates to release loaded ICG and siCD24. The core mechanism involves ultrasound‐guided sonodynamic therapy by ICG and CD24 knockdown by siCD24, both activating the p53 axis

Electrochemically Driven Regioselective Radical Functionalization of Allenes: Scope and Mechanistic Insights

Advanced Science, EarlyView.
Allenes emerge as powerful platforms for electrochemical functionalization through radical pathways. Selective radical addition at the central carbon triggers anodic oxidation and intramolecular cyclization, enabling efficient synthesis of oxazolines and oxazolidine‐2‐imines without external oxidants.

Nickel‐Catalyzed Three‐Component Difluoroalkylation‐Amination for the Direct Access to Anti‐Inflammatory β‐Difluoroalkyl Amines

Advanced Science, EarlyView.
A nickel‐catalyzed three‐component reductive fluoroalkylation‐amination strategy of N‐vinylamides for the direct access to the α‐amidyl‐β‐difluoroalkyl amines was reported here. The synthetic method features with broad substrate scope, mild conditions, high functional group tolerance, and convenience to handle.
