A method has been developed for obtaining thioamides of 5-amino-2-aryl-2H-1,2,3-triazole-4-carboxylic acid. Their heterocyclization reactions with bifunctional reagents has been studied. New heterocyclic polycyclic ensembles have been synthesized containing a 1,2,3-triazole fragment, a thiazole, ...

The iodide effects in organic reactions have been summarized elsewhere22. The solvent effect was also studied in this work. When the reaction was conducted in hexanoic acid, instead of AcOH, the reaction took place but the yield was not as high as that in AcOH (entries 2, 19). When ...
Reactions of Chromyl Chloride with Carboxylic Acids and Carboxylic Acid Anhydrides Chromyl Chloride reacts with carboxylic acids [RCOOH where R = C2H5, n-C3H7, CH2CI, CHCl2 and CCI3] to give reduced chromium(III) carboxylates, [Cr3 O(OOCR... R Kapoor,P Kapoor,R Sharma - 《Zeitschrift...
We posited that a carboxylic acid could be directly used as a latent electrophile (C-terminus) rather than a nucleophile (O-terminus) in cross-coupling. This could simplify and upgrade ketone synthesis from carboxylic acids and organic halides13. Very recently, our group and Doyle et al. ...
thereby constructing various complex and fine organic molecules. In chemical synthesis, the carboxylic acid groups of DusQ 21 carboxylic acid can participate in various important reactions, such as esterification and amidation. Through esterification reaction, it can combine with alcohol compounds to gener...
