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

Di-tert-butyl tricarbonate extrudes carbon dioxide in the presence of various catalysts to form di-tert-butyl dicarbonate. [2] Long-chain carbon dioxide oligomers are likewise expected to decompose exothermically .

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]
dimethyl dicarbonate H 3 C−C 2 O 5 −CH 3; diethyl dicarbonate C 2 H 5 −C 2 O 5 −C 2 H 5; 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 ...
For this reason di-tert-butyl peroxide is commonly used as a radical initiator in organic synthesis and polymer chemistry. The decomposition reaction proceeds via the generation of methyl radicals. (CH 3) 3 COOC(CH 3) 3 → 2 (CH 3) 3 CO • (CH 3) 3 CO • → (CH 3) 2 CO + CH • 3 2 CH • 3 → C 2 H 6
The addition of tri-tert-butyl cyclopropenium ion produces the thermally stable cyclopropenyl phosphine intermediate. Upon irradiation with 254 nm light in the presence of triflic acid and either tetra- n -butyl ammonium chloride or tetramethylammonium fluoride , the anthracene leaving group is forced out, leaving a halogenated phosphine.
