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.
2-tert-Butoxy-2-methylpropane Di-tert-butyl ether. Identifiers ... Except where otherwise noted, data are given for materials in their standard state (at 25 °C ...
tert-Butanesulfinamide (also known as 2-methyl-2-propanesulfinamide or Ellman's sulfinamide) is an organosulfur compound and a member of the class of sulfinamides. Both enantiomeric forms are commercially available and are used in asymmetric synthesis as chiral auxiliaries , often as chiral ammonia equivalents for the synthesis of amines .
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.
[25] MTBE forms azeotropes with water (52.6 °C; 96.5% MTBE) [26] and methanol (51.3 °C; 68.6% MTBE). [27] The solubility of water in MTBE is reported to be 1.5 g/100g at 23 °C. [26] In an investigational medical procedure called contact dissolution therapy, MTBE is injected directly into the gallbladder to dissolve cholesterol gallstones.
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
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.
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.
