Nasielski, J.; Heilporn, S.; Nasielski-Hinkens, R.; Tinant, B.; Declercq, J. P. published an article in 1989, the title of the article was An unexpected ring-opening in the Reissert reaction on 2,3-diphenylquinoxaline N-oxide.SDS of cas: 62163-09-1 And the article contains the following content:
When quinoxaline-N-oxide is reacted with KCN and BzCl in H2O or MeOH; the products are 2-, 5- and 6-chloroquinoxaline and small amounts of 2-cyanoquinoxaline. Using three equivalent of Me3SiCN instead of KCN, and CH2Cl2 as the solvent, leads to a 72% yield of 2-cyanoquinoxaline. The reaction of Me3SiCN and BzCl with 2,3-diphenylquinoxaline-N-oxide leads to 2-Bz2NC6H4N:CPhCN (I). The structure of I is based on spectroscopic data and on an X-ray crystallog. anal. The experimental process involved the reaction of 5-Chloroquinoxaline(cas: 62163-09-1).SDS of cas: 62163-09-1
