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 .
2,3-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 .
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.
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.
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 ...
Firstly, 2,4-dimethyl-6-tert-butylphenol is reacted with formaldehyde and HCl (Blanc reaction) to generate a chloromethyl group in the less hindered meta position. This intermediate then reacts with cyanuric acid to give the desired product.
Transfer hydrogenation usually occurs at mild temperature and pressure conditions using organic or organometallic catalysts, many of which are chiral, allowing efficient asymmetric synthesis. It uses hydrogen donor compounds such as formic acid, isopropanol or dihydroanthracene, dehydrogenating them to CO 2, acetone, or anthracene respectively. [1]
