JASOURI, S.; KHALAFY, J.; BADALI, M.  and  PRAGER, R.H.. Synthesis of 9H-indeno [1, 2-b] pyrazine and 11H-indeno [1, 2-b] quinoxaline derivatives in one-step reaction from 2-bromo-4-chloro-1-indanone. S.Afr.j.chem. (Online) [online]. 2011, vol.64, pp.105-107. ISSN 1996-840X.

The reaction of 2-bromo-4-chloro-1-indanone with 2,3-diaminomaleonitrile, benzene-1,2-diamine and 4-methylbenzene-1,2-diamine in glacial acetic acid gave 8-chloro-9H-indeno[1,2-b]pyrazine-2,3-dicarbonitrile, 1-chloro-11H-indeno[1,2-b]quinoxa-line and 1-chloro-7-methyl-11H-indeno[1,2-b]quinoxaline, respectively, in good yield.

Keywords : 2-bromo-4-chloro-1-indanone; diaminopyridine; indeno; quinoxaline; indeno; pyrazine; debromination.
