Synthesis of bis-quinoxaline derivatives using Tonsil clay as a catalyst

M. Badali, J. Khalafy, M. Aghazadeh, R. H. Prager

Abstract


A convenient and efficient synthesis of new bis-quinoxaline is described, involving condensation of 1,2-diamines with 9-ethyl-3,6-di(1,2-dioxoethyl)carbazole in the presence of Tonsil clay, a readily  available and inexpensive catalyst. The structures of all new products were identified by 1H-NMR, 13C-NMR and FT-IR spectral data and microanalysis.

 

KEY WORDS: bis-Quinoxaline, bis-Glyoxal, Green chemistry, 1,2-Diamine, Tonsil clay
