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. [4]
tert-Butylbenzene is an organic compound classified as an aromatic hydrocarbon. Its structure consists of a benzene ring substituted with a tert -butyl group . It is a flammable colorless liquid which is nearly insoluble in water but miscible with organic solvents.
The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.
Dimethylbutene is an alkene with a molecular formula C 6 H 12. It has the following possible structural isomers: 2,3-Dimethyl-1-butene; 3,3-Dimethyl-1-butene;
2,3-Dimethyl-1-butene is an organic compound with the formula CH 2 =C(CH 3)CH(CH 3) 2. Like the other isomers of dimethylbutene, it is a colorless liquid. Together with 2,3-dimethyl-2-butene it can be produced by dimerization of propylene. It is a precursor to the commercial fragrance tonalide. [1]
Pinacolone (3,3-dimethyl-2-butanone) is an important ketone in organic chemistry. It is a colorless liquid with a slight peppermint or camphor odor. It is a precursor to triazolylpinacolone in the synthesis of the fungicide triadimefon and in synthesis of the herbicide metribuzin. The molecule is an unsymmetrical ketone. The α-methyl group can ...
Thexylborane is a borane with the formula [Me 2 CHCMe 2 BH 2] 2 (Me = methyl). The name derives from "t-hexylborane" (although the group is not the standard tert-hexyl group), and the formula is often abbreviated ThxBH 2. A colorless liquid, it is a monoalkylborane. It is produced by the hydroboration of tetramethylethylene: [1]
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] The psychotropic effects of TAA and ethanol are similar, though distinct.
