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.

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 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.
P 4-t-Bu is a readily accessible chemical from the group of neutral, peralkylated sterically hindered polyaminophosphazenes, which are extremely strong bases but very weak nucleophiles, with the formula (CH 3) 3 C−N=P(−N=P(−N(CH 3) 2) 3) 3. "t-Bu" stands for tert-butyl (CH 3) 3 C –. "P 4" stands for the fact that this molecule has 4 ...
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).
tert-Butyldimethylsilyl chloride is an organosilicon compound with the formula (Me 3 C)Me 2 SiCl (Me = CH 3). It is commonly abbreviated as TBSCl or TBDMSCl. It is a chlorosilane containing two methyl groups and a tert-butyl group. As such it is more bulky that trimethylsilyl chloride. It is a colorless or white solid that is soluble in many ...
The by-products are dimethyl sulfide (Me 2 S), carbon monoxide (CO), carbon dioxide (CO 2) and – when triethylamine is used as base – triethylammonium chloride (C 6 H 15 NHCl). The related N-tert-Butylbenzenesulfinimidoyl chloride combines both the sulfur(IV), the base, and the activating Lewis acid in one molecule.
