Chemistry is traditionally divided into organic and inorganic chemistry. Safety of 6-Bromoquinoxalin-2(1H)-one, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 55687-34-8
Photoinitiated decarboxylative C3-difluoroarylmethylation of quinoxalin-2(1: H)-ones with potassium 2,2-difluoro-2-arylacetates in water
An efficient and green strategy for the preparation of C3-difluoroarylmethylated quinoxalin-2(1H)-one via a visible-light-induced decarboxylative C3-difluoroarylmethylation of quinoxalin-2(1H)-one with potassium 2,2-difluoro-2-arylacetate in water at room temperature was developed. This photoinduced reaction generated the desired products in good yields under simple and mild conditions.
If you are interested in 55687-34-8, you can contact me at any time and look forward to more communication. Safety of 6-Bromoquinoxalin-2(1H)-one
