Abstract
(COCl)2 [79-37-8] C2Cl2O2 (MW 126.92) InChI = 1S/C2Cl2O2/c3-1(5)2(4)6 InChIKey = CTSLXHKWHWQRSH-UHFFFAOYSA-N (DMF) [68-12-2] C3H7NO (MW 73.11) InChI = 1S/C3H7NO/c1-4(2)3-5/h3H,1-2H3 InChIKey = ZMXDDKWLCZADIW-UHFFFAOYSA-N (versatile agent combination for in situ generation of Vilsmeier reagent used in preparation of carboxylic acid chlorides and other acid derived products,1 phosphonic acid chlorides,2 β-chloro enones,3 ketoximes4 and formyl derivatives5) Physical Data: see entries for Oxalyl Chloride and N,N‐Dimethylformamide. Form Supplied in: generated in situ under anhydrous conditions from oxalyl chloride and either catalytic or stoichiometric dimethylformamide, typically in halogenated solvents such as dichloromethane; acetonitrile, or hexane. The intermediate dimethylforminium chloride (DMFCl) can be isolated as a hygroscopic solid, mp 140 °C (see also Thionyl Chloride, Phosphorus Oxychloride). Handling, Storage, and Precautions: (see also Oxalyl Chloride); reagent generated in situ under anhydrous conditions; corrosive, toxic. Oxalyl chloride should be used in the fume hood.
