Sulfonic acid functionalized mesoporous SBA-15 for one-pot synthesis of substituted aryl-14H-dibenzo xanthenes and bis(indolyl) methanes

The comparative catalytic activity studies of biologically and industrially important compounds such as Xanthenes and bis (indolyl) methanes were evaluated over propylsulfonic acid functionalized SBA-15/SO(3)H. The material was characterized via standard characterization techniques such as Powder X-ray diffraction, FTIR. Temperature programmed desorption studies of NH(3). The catalytic performance of SBA/SO(3)H under environmentally benign conditions results in high yield of xanthenes compared to bis (indolyl) methanes and finally the mechanism for both the reactions were proposed.
