Resumen

GHORBANI-VAGHEI, Ramin  y  VEISI, Hojat. One-pot synthesis of substituted pyrroles with N,N,N',N' -tetrachlorobenzene-1,3-disulphonamide and N,N'-Diiodo-N,N'-1,2-ethanediylbis (p-toluenesulphonamide) as novel catalytic reagents. S.Afr.j.chem. (Online) [online]. 2009, vol.62, pp.33-38. ISSN 1996-840X.

In this research, N/N/N',N'-tetrachlorobenzene-1,3-disulphonamide as novel catalytic reagent and N,N'-diiodo-N,N'-1,2-ethanediylbis(p-toluenesulphonamide) as new catalyst were used for the synthesis of N-substituted pyrroles in good to excellent yields under mild conditions. These reusable reagents were compared with existing reagents and it is clear that this study is a welcome addition in the field of pyrrole synthesis.
