some polymeric coatings and adhesives. They are generated by hydrogen-atom abstraction from thiols using initiators such as AIBN: RN=NR → 2 R• + N2 R•...

Metal-Hydride Hydrogen Atom Transfer (MHAT) is a process where a metal hydride (M–H) transfers a hydrogen atom (H•) to an alkene, forming a carbon-centered...

(87 kcal/mol), while for CH3O−H, the BDE is 440 kJ/mol (110 kcal/mol). Hydrogen-atom abstraction from a thiol gives a thiyl radical with the formula RS•, where...

Roberts and his colleagues, where a normally slow single-step hydrogen atom abstraction (HAT) reaction from an electron rich C-H bond can be split into...

[RCO]+[SbCl6]− Acyl radicals are readily generated from aldehydes by hydrogen-atom abstraction. However, they undergo rapid decarbonylation to afford the alkyl...

species can serve the same function. In hydrogenation, bonds like C=C are reduced by transfer of hydrogen atoms. "Redox" is a portmanteau of "reduction"...

Combustion of hydrocarbons is thought to be initiated by hydrogen atom abstraction (not proton abstraction) from the fuel to oxygen, to give a hydroperoxide...

to Ag(2+) under the acidic reaction conditions. This induces a hydrogen atom abstraction by the silver, followed by radical decarboxylation. The carbon-centered...
