Techniques for postcolumn derivatization in gas chromatography/mass spectrometry
Ligon Jr., Woodfin V.,Grade, Hans
, p. 255 - 261 (1991)
The connection of the output of a conventional split-type capillary GC (gas chromatography) injector to the region between a capillary gas chromatograph and a mass spectrometer has allowed the addition of reagents to this region for purposes of postcolumn
Benzoic acid-catalyzed transamidation reactions of carboxamides, phthalimide, ureas and thioamide with amines
Wu, Ji-Wei,Wu, Ya-Dong,Dai, Jian-Jun,Xu, Hua-Jian
supporting information, p. 2429 - 2436 (2014/09/30)
An efficient and simple method for the transamidation of carboxamides, phthalimide, ureas and thioamide with amines catalyzed by commercially available benzoic acid under metal-free conditions is described. Furthermore, to the best of our knowledge, this is the first report about the transamidation of an aromatic thioamide with amines.
A mild and efficient procedure for the preparation of acid chlorides from carboxylic acids
Jang, Doo Ok,Park, Doo Jin,Joonggon, Kim
, p. 5323 - 5326 (2007/10/03)
Various carboxylic acids are converted into the corresponding acid chlorides by treatment with trichloroacetonitrile and triphenylphosphine in methylene chloride at room temperature. Aryl acids show higher reactivity than alkyl acids under the conditions.
