Abstract

Abstract Poly (N, N′-dibromo-N-ethyl-benzene-1, 3-disulphonamide)[PBBS] and N, N, N′, N′-tetrabromobenzene-1, 3-disulphonamide [TBBDA] were used as efficient catalysts for the synthesis of quinoxaline derivatives in excellent yields from 1, 2-diamines and 1, 2- dicarbonyls under aqueous and solvent-free conditions. Graphical Abstract Poly (N, N′- dibromo-N-ethyl-benzene-1, 3-disulphonamide)[PBBS] and N, N, N′, N′- ...
