And the article was included in Journal of Organic Chemistry in 2022.Safety of 6-Chloroquinoxaline This article mentions the following:
A metal-free environmentally benign, simple, and efficient transfer hydrogenation process of quinoxaline was developed using the HBpin reagent as a hydrogen source. This reaction was compatible with a variety of quinoxalines offering the desired tetrahydroquinoxalines in moderate-to-excellent yields with Bu4NBr as a noncorrosive and low-cost catalyst. In the experiment, the researchers used many compounds, for example, 6-Chloroquinoxaline (cas: 5448-43-1Safety of 6-Chloroquinoxaline).
6-Chloroquinoxaline (cas: 5448-43-1) 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.Safety of 6-Chloroquinoxaline
