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-Butyl alcohol is used as a solvent, ethanol denaturant, paint remover ingredient, and gasoline octane booster and oxygenate.It is a chemical intermediate used to produce methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) by reaction with methanol and ethanol, respectively, and tert-butyl hydroperoxide (TBHP) by reaction with hydrogen peroxide.
tert-Butylthiol is the main ingredient in many gas odorant blends. [citation needed] It is always utilized as a blend of other compounds, typically dimethyl sulfide, methyl ethyl sulfide, tetrahydrothiophene or other mercaptans such as isopropyl mercaptan, sec-butyl mercaptan and/or n-butyl mercaptan, due to its rather high melting point of −0.5 °C (31.1 °F).
The methyl group in toluene is small and will lead the ortho product being the major product. On the other hand, the t-butyl group is very bulky (there are 3 methyl groups attached to a single carbon) and will lead the para product as the major one.
The homologous series of P 1 to P 7 polyaminophosphazenes [1] [2] of the general formula [() =] = with preferably methyl groups as R 1, a methyl group or tert-butyl group as and even-numbered x between 0 and 6 (P 4-t-Bu: R 1 = Me, R 2 = t-Bu and x = 3) [3] has been developed by Reinhard Schwesinger; the resulting phosphazene bases are therefore ...

There are also a large number of branched or ring alkanes that have specific names, e.g., tert-butyl, bornyl, cyclohexyl, etc.There are several functional groups that contain an alkene such as vinyl group, allyl group, or acrylic group.
One example of a moderately stable thiosulfinate is the tert-butyl derivative, (CH 3) 3 CS(O)SC(CH 3) 3. This thiosulfinate can be obtained in optical purity by catalytic asymmetric oxidation of di-tert-butyl disulfide with hydrogen peroxide. [17]
