hydrogensulfate has emerged as a promising solid acid catalyst for acid catalyzed reactions.24–30 As a continuation of our study in catalytic ability of the ferric hydrogensulfate,25–29 this work reports an efficient, mild and convenient method for the synthesis of some novel 14-substituted-14Hdibenzo[a,j]xanthenes in the presence of silica-supported ferric hydrogensulfate (SFH) Fe(HSO4)3/SiO2 (10 mol%)
