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.
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.
tert-Butyl alcohol is the simplest tertiary alcohol, with a formula of (CH 3) 3 COH (sometimes represented as t-BuOH). Its isomers are 1-butanol, isobutanol, and butan-2-ol. tert-Butyl alcohol is a colorless solid, which melts near room temperature and has a camphor-like odor. It is miscible with water, ethanol and diethyl ether.
Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a high molecular weight additive, with low volatility. It is well suited to stabilising polyolefins against degradation caused by long term heat aging. [1] It is an approved food contact material in the US. [2]
5-tert-Butyl-m-xylene is a chemical compound from the family of alkylbenzenes and is a colorless liquid at room temperature. It can be used for the synthesis of polyalkylated diaryl disulfides such as bis(4-tert-butyl-2,6-dimethylphenyl) disulfide and bis(2,4,6)-triisopropylphenyl) disulfide.
This compound is conveniently prepared by alkylation of cyclobutadiene with tert-butyl bromide under phase-transfer conditions. [2] [1] Illustrative of the unusual complexes made possible with these bulky ligands is molecular iron nitrido complex (t Bu 3 C 5 H 2) 2 Fe 2 N 2. [3] In contrast to (C 5 Me 5) 2 Ir 2 Cl 4, (t Bu 3 C 5 H 2)IrCl 2 is ...
4-tert-Butylphenol is an organic compound with the formula (CH 3) 3 CC 6 H 4 OH. It is one of three isomeric tert-butyl phenols. It is a white solid with a distinct phenolic odor. It dissolves in basic water. [2]
