  2. Ester - Wikipedia

    en.wikipedia.org/wiki/Ester

    An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′). [1]

    en.wikipedia.org/wiki/List_of_esters

    An ester of carboxylic acid. R stands for any group (organic or inorganic) and R′ stands for organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).

  4. Ortho ester - Wikipedia

    en.wikipedia.org/wiki/Ortho_ester

    The general formula of orthoesters. In organic chemistry, an ortho ester is a functional group containing three alkoxy groups attached to one carbon atom, i.e. with the general formula RC(OR') 3. Orthoesters may be considered as products of exhaustive alkylation of unstable orthocarboxylic acids and it is from these that the name 'ortho ester ...

  5. Nitrate ester - Wikipedia

    en.wikipedia.org/wiki/Nitrate_ester

    In organic chemistry, a nitrate ester is an organic functional group with the formula R−ONO 2, where R stands for any organyl group. They are the esters of nitric acid and alcohols. A well-known example is nitroglycerin, which is not a nitro compound, despite its name.

  6. Organosulfate - Wikipedia

    en.wikipedia.org/wiki/Organosulfate

    In organosulfur chemistry, organosulfates are a class of organic compounds sharing a common functional group with the structure R−O−SO − 3. The SO 4 core is a sulfate group and the R group is any organic residue. All organosulfates are formally esters derived from alcohols and sulfuric acid (H 2 SO 4) although many

  7. Phosphite ester - Wikipedia

    en.wikipedia.org/wiki/Phosphite_ester

    The general structure of a phosphite ester showing the lone pairs on the P. In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR) 3. They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite ...

  8. Acetoacetic acid - Wikipedia

    en.wikipedia.org/wiki/Acetoacetic_acid

    Acetoacetic esters are used for the acetoacetylation reaction, which is widely used in the production of arylide yellows and diarylide dyes. [3] Although the esters can be used in this reaction, diketene also reacts with alcohols and amines to the corresponding acetoacetic acid derivatives in a process called acetoacetylation .

  9. Sulfonate - Wikipedia

    en.wikipedia.org/wiki/Sulfonate

    In organosulfur chemistry, a sulfonate is a salt, anion or ester of a sulfonic acid. Its formula is R−S(=O) 2 −O −, containing the functional group −S(=O) 2 −O −, where R is typically an organyl group, amino group or a halogen atom. Sulfonates are the conjugate bases of sulfonic acids.
