Di-tert-butyl dicarbonate is a reagent widely used in organic synthesis. [1] Since this compound can be regarded formally as the acid anhydride derived from a tert-butoxycarbonyl (Boc) group, it is commonly referred to as Boc anhydride. This pyrocarbonate reacts with amines to give N-tert-butoxycarbonyl or so-called Boc
Add the amine to sodium hydroxide and di-tert-butyl dicarbonate in water and THF at 0 °C then warm to ambient temperature. [13] Heating a mixture of the amine to be protected and di-tert-butyl dicarbonate in a biphasic mixture of chloroform and aqueous sodium bicarbonate at reflux for 90 minutes. [14]
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

di-tert-butyl dicarbonate (H 3 C−) 3 C−C 2 O 5 −C(−CH 3) 3, also known as Boc anhydride. It is one of the oxocarbon anions, consisting solely of oxygen and carbon. The anion has the formula − O−C(=O)−O−C(=O)−O − or C 2 O 2− 5. Dicarbonate salts are apparently unstable at ambient conditions, but can be made under pressure ...
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 ...
tert-Butyl acetate, t-butyl acetate or TBAc is a colorless flammable liquid with a camphor- or blueberry-like smell. It is used as a solvent in the production of lacquers, enamels, inks, adhesives, thinners and industrial cleaners.
Each HHB of the tert-butyl network were calculated (in absence of steric repulsion) to contribute 0.7 kcal/mol of stabilization. Calculations with one of the tert-butyl substituents with a methyl, ethyl, or isopropyl group result in net repulsion due to the loss of HHBs. [26] In total, this forms the basis of the corset effect. [5]
