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
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.
tert-Butyloxycarbonyl protecting group. The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] (BOC group) is an acid-labile protecting group used in organic synthesis. The BOC group can be added to amines under aqueous conditions using di-tert-butyl dicarbonate in the presence of a base such as sodium hydroxide:
Density: 1.101 g/mL at 25 °C 1.121 g/mL at 20 °C Boiling point: 93 to 94 °C (199 to 201 °F; 366 to 367 K) at 24 hPa ... Di-tert-butyl dicarbonate Dimethyl ...
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]
An important example is di-tert-butyl tricarbonate (H 3 C−) 3 C−C 3 O 7 −C(−CH 3) 3, an intermediate in the synthesis of di-tert-butyl dicarbonate. [1] The term tricarbonate is sometimes used for salts that contain three carbonate dianions in their covalent structure or stoichiometric formula, such as cerium tricarbonate Ce 2 (CO 3) 3.
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.
The unit cell volume is 272.4 Å 3 and density 7.59. [4] SrC 2 O 5 (strontium dicarbonate) is very similar to the lead compound, and also has monoclinic structure with space group P2 1 /c and four formula units per unit cell. At 30 GPa the unit cell has a=4.736 b=8.175 c=7.140 Å and β=91.34°. The unit cell volume is 276.3 Å 3 and density 4. ...
