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.
