Cyalume Synthesis Overview The synthetic reaction is shown below. Oxalyl chloride was reportedly used in the first synthesis of dioxane tetraketone (C 4 O 6), an oxide of carbon. Application Oxalyl chloride may be used in the following processes: • Preparation of Mosher′s acid chloride by reacting with Mosher′s acid in the presence of DMF. Recent Literature. Molecular Weight 126.93 . Beilstein/REAXYS Number 1361988 . - Find MSDS or SDS, a COA, data sheets and more information. Oxalyl chloride is a chemical compound with the formula (COCl) 2. MDL number MFCD00000704. In March 2000, a Malaysia Airlines Airbus A330-300 was damaged beyond repair after a cargo of prohibited oxalyl chloride (falsely declared as hydroxyquinoline) leaked into the cargo bay. Precautions . Linear Formula ClCOCOCl . Oxalyl chloride is a commonly used chlorinating reagent that can be prepared by the reaction of oxalic acid and phosphorus pentachloride. Carboxylic acids react with thionyl chloride (SOCl 2) or oxalyl chloride (C 2 O 2 Cl 2) to form acid chlorides.Typically the reactions occur in the presence of a proton scavanger like pyridine to minimize unwanted side reactions. A. I. Mikhaleva, A. V. Ivanoc, E. V. Skital'tseva, I. Use of oxalyl chloride in toluene has been reported for the synthesis of bis(2,4,6-trichlorophenyl) oxalate (TCPO), in this case a 2M solution was prepared and added to 3.5mmol of 2,4,6-trichlorophenol in the presence of triethylamine. CAS 79-37-8, EC Number 201-200-2, chemical formula ClCOCOCl. 9. Acid Halide Synthesis. [3] It can be prepared by treating oxalic acid with phosphorus pentachloride. Oxalyl chloride for synthesis. An alternative approach involves the reaction of ethyl 4-pyrazolecarboxylates (COCl) 2 Oxalyl Chloride [] is also commonly used to convert carboxylic acids to acid chlorides.The process typically involves stirring the substrate in DCM at RT with (COCl)2 and a catalytic amount of DMF. PubChem Substance ID 57654494 Oxalyl chloride 2 (the blue reactant) is a symmetric acid chloride that is highly electrophilic and is very reactive because of the chloride leaving group. 1-Vinylpyrroles are formylated by the N,N-dimethyl­formamide/oxalyl chloride reagent system to give the corresponding 1-vinylpyrrole-2-carbaldehydes in good yields in short reaction times. gave only monocarboxylic derivative even with a large excess of oxalyl chloride and prolonged reaction duration.

One oxalyl chloride reacts with two molecules of phenol 1 (green chemical) to give the diester 4, which is a cyalume. This colourless, sharp-smelling liquid, the diacyl chloride of oxalic acid, is a useful reagent in organic synthesis.
