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:
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
The tert-butyloxycarbonyl group is marked blue. Amines have a special importance in peptide synthesis, but are a quite potent nucleophile and also relatively strong bases. These characteristics imply that new protecting groups for amines are always under development. [47] Amine groups are primarily protected through acylation, typically as a ...
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F). [3]
2,6-Di-tert-butylphenol is an organic compound with the structural formula 2,6-((CH 3) 3 C) 2 C 6 H 3 OH. This colorless solid alkylated phenol and its derivatives are used industrially as UV stabilizers and antioxidants for hydrocarbon -based products ranging from petrochemicals to plastics. [ 1 ]
Heating the product at 60 °C for 3 hours causes the expulsion of a di-tert-butylacetylene and the reformation of P-P bonds. Another reaction pathway involves the addition of 3 equivalents of CO to the product, leading to the production of Ni(IMes)(CO) 3 and the ladderane-like compound described at the beginning of this section.
Di-tert-butyl-iminodicarboxylate is an organic compound that can be described with the formula [(CH 3) 3 COC(O)] 2 NH. It is a white solid that is soluble in organic solvents. The compound is used as a reagent for the preparation of primary amines from alkyl halides. [1] It was popularized as an alternative to the Gabriel synthesis for the same ...
it is an ingredient in Photo-Flo, a solution used in photographic processing to prevent minerals from water being deposited on the film after drying. Apart from laboratory use, Triton X-100 can be found in several types of cleaning compounds, [ 7 ] ranging from heavy-duty industrial products to gentle detergents.
