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.
The terms sec and tert are considered obsolete and should only be used for unsubstituted sec-butoxy, sec-butyl [26] [27] or tert-butyl groups. [ 28 ] [ 27 ] There are various spellings such as "sec-butyl", "s-butyl", "sBu" or "bus" which are also considered obsolete.
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).
Butan-2-ol, or sec-butanol, is an organic compound with formula C H 3 CH(OH)CH 2 CH 3. Its structural isomers are 1-butanol , isobutanol , and tert -butanol . 2-Butanol is chiral and thus can be obtained as either of two stereoisomers designated as ( R )-(−)-butan-2-ol and ( S )-(+)-butan-2-ol.
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.
n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3. A colorless, flammable liquid, it is the ester derived from n - butanol and acetic acid . It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.
Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol) is an organic compound with the formula (CH 3) 2 CHCH 2 OH (sometimes represented as i-BuOH).This colorless, flammable liquid with a characteristic smell is mainly used as a solvent either directly or as its esters.
tert-Butyl isocyanide is an organic compound with the formula Me 3 CNC (Me = methyl, CH 3). It is an isocyanide , commonly called isonitrile or carbylamine, as defined by the functional group C≡N-R. tert -Butyl isocyanide, like most alkyl isocyanides, is a reactive colorless liquid with an extremely unpleasant odor.
