Bistrifluoromethylated organocuprate [Ph4P]+[Cu(CF3)2]–: synthesis, characterization and its application for trifluoromethylation of activated heteroaryl bromides, chlorides and iodides was written by Liu, He;Shen, Qilong. And the article was included in Organic Chemistry Frontiers in 2019.Name: Ethyl 3-chloroquinoxaline-2-carboxylate This article mentions the following:
The synthesis and characterization of a bistrifluoromethylated organocuprate [Ph4P]+[Cu(CF3)2]– and its reactions with a variety of activated heteroaryl bromides, chlorides and iodides were described. These results showed that complex [Ph4P]+[Cu(CF3)2]– can serve as a trifluoromethylating reagent. In the experiment, the researchers used many compounds, for example, Ethyl 3-chloroquinoxaline-2-carboxylate (cas: 49679-45-0Name: Ethyl 3-chloroquinoxaline-2-carboxylate).
Ethyl 3-chloroquinoxaline-2-carboxylate (cas: 49679-45-0) belongs to quinoxaline derivatives. Condensed heterocycles of quinoxalines have become attractive targets in synthetic and medicinal chemistry due to their significant biological activities. They are well-known for application in organic light emitting devices, polymers and pharmaceutical agents. The quinoxaline-containing polymers are applicable in optical devices due to their thermal stability and low band gap.Name: Ethyl 3-chloroquinoxaline-2-carboxylate
