Di-tert-butylcyclopentadiene is an organic compound with the formula (Me 3 C) 2 C 5 H 4, where Me = methyl.It is a colorless liquid that is soluble in organic solvents. The compound is the conjugate acid of the di-tert-butylcyclopentadienyl ligand, (Me 3 C) 2 C 5 H 3 − [1] (sometimes abbreviated Cp ‡−).
The intermediate in this synthesis is di-tert-butylcyclopentadiene. 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]
2,2,4,4-Tetramethyl-3-t-butyl-pentane-3-ol or tri-tert-butylcarbinol is an organic compound with formula C 13 H 28 O, ((H 3 C) 3 C) 3 COH, or t Bu 3 COH. [1] It is an alcohol that can be viewed as a structural analog of a tridecane isomer ( 2,2,4,4-tetramethyl-3- t -butylpentane ) where the central hydrogen has been replaced by a hydroxyl group ...
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.

Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F).

tert-Butyl bromide (also referred to as 2-bromo-2-methylpropane) is an organic compound with the formula Me 3 CBr (Me = methyl). The molecule features a tert-butyl group attached to a bromide substituent. This organobromine compound is used as a standard reagent in synthetic organic chemistry. It is a colorless liquid.
For this reason di-tert-butyl peroxide is commonly used as a radical initiator in organic synthesis and polymer chemistry. The decomposition reaction proceeds via the generation of methyl radicals. (CH 3) 3 COOC(CH 3) 3 → 2 (CH 3) 3 CO • (CH 3) 3 CO • → (CH 3) 2 CO + CH • 3 2 CH • 3 → C 2 H 6
