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.
2,4-Dimethyl-6-tert-butylphenol is the organic compound with the formula Me 2 (tert-Bu)C 6 H 2 OH (Me = methyl, tert-Bu = tertiary butyl). It is a colorless oil that is classified as an alkylated phenol. [1]
The chemical synthesis of BHT in industry has involved the reaction of p-cresol (4-methylphenol) with isobutylene (2-methylpropene), catalyzed by sulfuric acid: [11] CH 3 (C 6 H 4)OH + 2 CH 2 =C(CH 3) 2 → ((CH 3) 3 C) 2 CH 3 C 6 H 2 OH. Alternatively, BHT has been prepared from 2,6-di-tert-butylphenol by hydroxymethylation or aminomethylation ...
