(matrix presented) Condensation of 2-fluorobenzonitriles with phenoxides affords 2-aryloxybenzonitriles that cyclize cleanly in trifluoromethanesulfonic acid at room temperature to give xanthone-iminium triflates. The C=N bond in these compounds is remark

Three dixanthones (1-3) and an unprecedented C3h-symmetric trixanthone (4) were synthesized through a three-step approach in overall yields above 63%. These compounds possessed a planar π-conjugated system and formed tight face-to-face columnar
