  2. Di-tert-butyl dicarbonate - Wikipedia

    en.wikipedia.org/wiki/Di-tert-butyl_dicarbonate

    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

    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:

  4. tert-Butyl alcohol - Wikipedia

    en.wikipedia.org/wiki/Tert-Butyl_alcohol

    The tert-butoxide is a strong, non-nucleophilic base in organic chemistry. It readily abstracts acidic protons from substrates, but its steric bulk inhibits the group from participating in nucleophilic substitution, such as in a Williamson ether synthesis or an S N 2 reaction. tert-Butyl alcohol reacts with hydrogen chloride to form tert-butyl ...

  5. Tricarbonate - Wikipedia

    en.wikipedia.org/wiki/Tricarbonate

    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.

    Bis(2,4-di-tert-butylphenyl) pentaerythritol diphosphite is an organophosphite used as a polymer stabilizer in plastics. Like other phosphite antioxidants it primarily acts to remove hydroperoxides and is typically used in combination with hindered phenolic antioxidants such as pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) .
