2. Scavenger (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Scavenger_(chemistry)

   In atmospheric chemistry, the most common scavenger is the hydroxyl radical, a short-lived radical produced photolytically in the atmosphere. It is the most important oxidant for carbon monoxide, methane and other hydrocarbons, sulfur dioxide, hydrogen sulfide, and most of other contaminants, removing them from the atmosphere.

4. Free-radical reaction - Wikipedia

   en.wikipedia.org/wiki/Free-radical_reaction

   A free-radical reaction is any chemical reaction involving free radicals. This reaction type is abundant in organic reactions . Two pioneering studies into free radical reactions have been the discovery of the triphenylmethyl radical by Moses Gomberg (1900) and the lead-mirror experiment [ 1 ] described by Friedrich Paneth in 1927.

5. 2-Methyl-2-butene - Wikipedia

   en.wikipedia.org/wiki/2-Methyl-2-butene

   2-Methyl-2-butene, 2m2b, 2-methylbut-2-ene, beta-isoamylene, or Trimmethylethylene is an alkene hydrocarbon with the molecular formula C 5 H 10.. Used as a free radical scavenger in trichloromethane (chloroform) and dichloromethane (methylene chloride).

6. Radical cyclization - Wikipedia

   en.wikipedia.org/wiki/Radical_cyclization

   The radical cyclization step usually involves the attack of a radical on a multiple bond. After this step occurs, the resulting cyclized radicals are quenched through the action of a radical scavenger, a fragmentation process, or an electron-transfer reaction. Five- and six-membered rings are the most common products; formation of smaller and ...

7. Free-radical theory of aging - Wikipedia

   en.wikipedia.org/wiki/Free-radical_theory_of_aging

   The free radical theory of aging states that organisms age because cells accumulate free radical damage over time. [1] A free radical is any atom or molecule that has a single unpaired electron in an outer shell. [2] While a few free radicals such as melanin are not chemically reactive, most biologically relevant free radicals are highly ...

8. Reactive oxygen species - Wikipedia

   en.wikipedia.org/wiki/Reactive_oxygen_species

   Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination). Effects of ROS on cell metabolism are well documented in a variety of species. [ 20 ] These include not only roles in apoptosis (programmed cell death) but also positive effects such as the induction of host defence [ 37 ] [ 38 ...

9. Living free-radical polymerization - Wikipedia

   en.wikipedia.org/wiki/Living_free-radical...

   Living free radical polymerization is a type of living polymerization where the active polymer chain end is a free radical. Several methods exist. Several methods exist. IUPAC recommends [ 1 ] to use the term " reversible-deactivation radical polymerization " instead of "living free radical polymerization", though the two terms are not synonymous.
