2-Phenyl-3-(sulfonamido)benzofurans are produced in a cascade reaction of N-(2,2-dichloro-2-phenylethylidene)arenesulfonamides with para-substituted phenols in the presence of the superacid H2SO4/P 4O10 system. A convenient synthetic approach to 2-aryl-3-(sulfonamido)benzofurans through a cascade reaction of available N-(2,2-dichloro-2-phenylethylidene)arenesulfonamides withpara-substituted phenols in the presence of the superacid H2SO4/P 4O10 system was developed.
