Peng, Yanqing published the artcileAmides by microwave-assisted dehydration of ammonium salts of carboxylic acids, Synthetic Route of 2447-79-2, the publication is Organic Preparations and Procedures International (2002), 34(1), 95-97, database is CAplus.
A direct and rapid procedure for the preparation of primary amides from ammonium salts of carboxylic acids in formamide under microwave irradiation is presented. Different types of carboxylic acids were converted to their corresponding amides by this procedure with satisfactory yields. The ammonium salts of carboxylic acids were formed in situ from ammonium bicarbonate and corresponding carboxylic acids. Formamide was suitable for this procedure both as a solvent and a dehydrating agent. This procedure compares favorably to other classical methods and it has the advantages of simple work-up, short reaction time, and the use of inexpensive and readily available reagents.
Organic Preparations and Procedures International published new progress about 2447-79-2. 2447-79-2 belongs to amides-buliding-blocks, auxiliary class Chloride,Amine,Benzene,Amide, name is 2,4-Dichlorobenzamide, and the molecular formula is C7H5Cl2NO, Synthetic Route of 2447-79-2.
