  2. Dimethyl oxalate - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_oxalate

    Dimethyl oxalate can be converted into ethylene glycol in high yields (94.7%) [10] [11] The methanol formed is recycled in the process of oxidative carbonylation. [12] Other plants with a total annual capacity of more than 1 million tons of ethylene glycol per year are planned. Decarbonylation gives dimethyl carbonate. [13]

  3. Carbonylation - Wikipedia

    en.wikipedia.org/wiki/Carbonylation

    Synthesis of acrylic acid using "Reppe chemistry"; a metal catalyst is required. The carbomethoxylation of ethylene to give methyl propionate: C 2 H 4 + CO + MeOH → MeO 2 CC 2 H 5. Methyl propionate ester is a precursor to methyl methacrylate. [10] Hydroesterification is like hydrocarboxylation, but it uses alcohols in place of water. [11]

    en.wikipedia.org/wiki/Oxalate

    Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4. This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4). It is a conjugate base of oxalic acid.

    The Seyferth–Gilbert homologation is a chemical reaction of an aryl ketone 1 (or aldehyde) with dimethyl (diazomethyl)phosphonate 2 and potassium tert-butoxide to give substituted alkynes 3. [1] [2] Dimethyl (diazomethyl)phosphonate 2 is often called the Seyferth–Gilbert reagent. [3] The Seyferth–Gilbert homologation

    en.wikipedia.org/wiki/Diphenyl_oxalate

    Diphenyl oxalate (trademark name Cyalume) is a solid whose oxidation products are responsible for the chemiluminescence in a glowstick. This chemical is the double ester of phenol with oxalic acid. Upon reaction with hydrogen peroxide, 1,2-dioxetanedione is formed, along with release of the two phenols. [2]
