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). It is also used to scavenge hypochlorous acid (HOCl) in the Pinnick oxidation.
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.

tert-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol. Historically, TAA has been used as an anesthetic [ 3 ] and more recently as a recreational drug . [ 4 ] TAA is mostly a positive allosteric modulator for GABA A receptors in the same way as ethanol . [ 5 ]
A Major Shift at Home Depot. In a surprising but not unheard-of move, Home Depot will require its out-of-store employees to work some in-store shifts.This is in the midst of a sales decline, so ...
It can be prepared by base-catalyzed isomerization of 2,3-dimethyl-1-butene. [2] Another route involves direct dimerization of propylene . [ 3 ] It can also be produced by photolysis of tetramethylcyclobutane-1,3-dione .
2-Methyl-2-butene is often used in this context: Resorcinol and sulfamic acid are also common scavenger reagents. [6] [7] Hydrogen peroxide (H 2 O 2) can be used as HOCl scavenger whose byproducts do not interfere in the Pinnick oxidation reaction: HOCl + H 2 O 2 → HCl + O 2 + H 2 O
Lindgren oxidation is a selective method for oxidizing aldehydes to carboxylic acids. [1] The reaction is named after Bengt O. Lindgren. The oxidation takes place in water containing solvent mixtures under slightly acidic conditions (pH 3–5) with sodium chlorite as oxidizer.
