Para-Selective Cu-Catalyzed C-H Aryloxylation of Electron-Rich Arenes and Heteroarenes was written by Sokolovs, Igors;Suna, Edgars. And the article was included in Journal of Organic Chemistry in 2016.Application In Synthesis of N,N-Diethylsalicylamide This article mentions the following:
Cu-catalyzed reaction of phenols with electron-rich arene or heteroarene ligands of unsym. diaryl-λ3-iodanes is a key step in the developed one-pot two-step method for intermol. para-selective C-H aryloxylation of heteroarenes and arenes. In the experiment, the researchers used many compounds, for example, N,N-Diethylsalicylamide (cas: 19311-91-2Application In Synthesis of N,N-Diethylsalicylamide).
N,N-Diethylsalicylamide (cas: 19311-91-2) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Application In Synthesis of N,N-Diethylsalicylamide
