Oxalyl chloride is an organic chemical compound with the formula Cl−C(=O)−C(=O)−Cl. This colorless, sharp-smelling liquid, the di acyl chloride of oxalic acid , is a useful reagent in organic synthesis .
Density: 1.3210 g/cm 3: Melting point: 34 to 37 °C (93 to 99 °F; 307 to 310 K) Boiling point: ... Oxalyl chloride is produced commercially from ethylene carbonate.
Thionyl chloride is an inorganic compound with the chemical formula SOCl 2.It is a moderately volatile, colourless liquid with an unpleasant acrid odour.Thionyl chloride is primarily used as a chlorinating reagent, with approximately 45,000 tonnes (50,000 short tons) per year being produced during the early 1990s, [5] but is occasionally also used as a solvent.
Peroxyoxalates are esters initially formed by the reaction of hydrogen peroxide with oxalate diesters or oxalyl chloride, with or without base, although the reaction is faster with base: Peroxyoxalates are intermediates that will rapidly transform into 1,2-dioxetanedione, another high-energy intermediate.
In organic chemistry, an acyl chloride (or acid chloride) is an organic compound with the functional group −C(=O)Cl. Their formula is usually written R−COCl , where R is a side chain . They are reactive derivatives of carboxylic acids ( R−C(=O)OH ).
A laboratory-safe variation masks the phosgene as oxalyl chloride. [5] Also, oxalyl chloride can be used to form acyl isocyanates from primary amides, which phosgene typically dehydrates to nitriles instead. [6] Another route to isocyanates entails addition of isocyanic acid to alkenes. Complementarily, alkyl isocyanates form by displacement ...
Thionyl chloride is commonly used to generate the acid chloride in situ, care being taken to maintain anhydrous conditions, as oxazolines can be ring-opened by chloride if the imine becomes protonated. [8] The reaction is typically performed at room temperature. If reagents milder than SOCl 2 are required, oxalyl chloride can be used. [9]
The mechanism of action is the insecticide binding at the GABA A site in the GABA-gated chloride channel (IRAC group 2A), which inhibits chloride flow into the nerve. [12]: 257 Other examples include dicofol, mirex, kepone, and pentachlorophenol. These can be either hydrophilic or hydrophobic, depending on their molecular structure. [13]
