Shuttle HAT for mild alkene transfer hydrofunctionalization
Nature CommunicationsHydrogen atom transfer (HAT) from a metal-hydride is a reliable and powerful method for functionalizing unsaturated C–C bonds in organic synthesis. Cobalt hydrides (Co–H) have garnered significant attention in this field, where the weak Co–H bonds are ...

THE DYNAMICS OF HYDROGEN ATOM ABSTRACTION FROM POLYATOMIC MOLECULES [PDF]
, 2004 The hydrogen atom abstraction reaction is an important fundamental process that is extensively involved in atmospheric and combustion chemistry. The practical significance of this type of reaction with polyatomic hydrocarbons is manifest, which has led to many kinetics studies.

Reactions of fluorine and bromine atoms [PDF]
, 1960 Hydrocarbons (chiefly the lower alkanes) have been fluorinated by a competitive method in a high vacuum, all glass, static system. Monofluorides formed by hydrogen abstraction from pairs of reactants have been measured by gas chromatography and ratios ...

Warm dust surface chemistry. H2 and HD formation [PDF]
arXiv, 2018 Molecular hydrogen (H2) is the main constituent of the gas in the planet-forming disks that surround many PMS stars. H2 can be incorporated in the atmosphere of the giant planets. HD has been detected in a few disks and can be considered the most reliable tracer of H2.

Virus‐Assembled Biofunctional Microarrays with Hierarchical 3D Nano‐Reticular Network
Advanced Functional Materials, EarlyView.Virus‐assembled microdots with a wrinkled pattern induced by the high‐pressure carbon dioxide method show a morphology similar to sunflowers. Abstract Three‐dimensional (3D) hierarchical wrinkled materials built with biological entities have so far remained exclusive to nature.

Catalytic Enantioselective Hydrogen Atom Abstraction Enables the Asymmetric Oxidation of Meso Diols [PDF]
Desymmetrization of meso diols is an important strategy for the synthesis of chiral oxygen-containing building blocks. Oxidative desymmetrization is an important subclass, but existing methods are often constrained by the need for activated alcohol ...

Gas-Phase Synthesis of Triphenylene (C18 H12 ). [PDF]
, 2019 For the last decades, the hydrogen-abstraction-acetylene-addition (HACA) mechanism has been widely invoked to rationalize the high-temperature synthesis of PAHs as detected in carbonaceous meteorites (CM) and proposed to exist in the interstellar medium (
