As originally determined by Staudinger, [7] oxalyl chloride reacts with water giving off gaseous products only: hydrogen chloride (HCl), carbon dioxide (CO2), and carbon monoxide (CO). [9] Other acyl chlorides hydrolyze with formation of hydrogen chloride …

To a mixture of the SM (603 mg, 2.35 mmol) and DMF (1 drop) in DCM (10 mL) was added (COCl)2 (592 mg, 4.70 mmol) at RT. The reaction mixture was stirred at RT for 2 h. The mixture was concentrated to provide the product as a yellow solid which was taken to the next step without further purification. [600 mg, 93%]

A detailed mechanism illustrating the conversion of a carboxylic acid to an acid chloride using oxalyl chloride [ (COCl)2].

Oxalyl Chloride [(COCl)2] 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. The reaction map is intended to provide insight into possible reactions one step before and after the title reaction.

In organic chemistry, the Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol (−OH) is oxidized to an aldehyde (−CH=O) or ketone (>C=O) using oxalyl chloride, dimethyl sulfoxide (DMSO) …

2001年4月15日 · 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.

It is shown that the reaction between carboxylic acid chlorides and dimethylformamide can take a previously unobserved course with formation of the corresponding carboxaldehydes. 2. Depending on the structure of the acid chloride, either transamidation or …

2010年3月5日 · In Co(NCS)2 DMF solution, cobalt(II) ions exist in the form of [CoNCS(DMF)5]+ and [Co(NCS)4]2- and the former is the main electroactive species for the deposition of cobalt.

Transformation of a carboxylic acid to the corresponding acid chloride using oxa-lyl chloride and catalytic amount of dimethyl formamide (DMF). It is a lot faster than without DMF, which generally needs reflux. (COCl)2, cat. DMF. oxalyl chloride.

2023年1月23日 · Carboxylic acids react with Thionyl Chloride (SOCl2 S O C l 2) to form acid chlorides. During the reaction the hydroxyl group of the carboxylic acid is converted to a chlorosulfite intermediate making it a better leaving group. The chloride anion produced during the reaction acts a nucleophile. Prof. Steven Farmer (Sonoma State University)
