摘要

Brønsted acidic ionic liquids (BAILs), 2-pyrrolidonium hydrogen sulfate and (4-sulfobutyl) tris (4-sulfophenyl) phosphonium hydrogen sulfate are found to be efficient catalysts for synthesis of 14-aryl-14H-dibenzo [a, i] xanthene-8, 13-dione, 3, 4-dihydro-1H-benzo [b] xanthene-1, 6, 11 (2H, 12H)-trione, and aryl-5H-dibenzo [b, i] xanthene-5, 7, 12, 14 (13H)- tetraone derivatives.
