چکیده
|
Nano-silica supported titanium tetrachloride (ticl4.sio2) wasprepared and used as an acid catalyst for the 14-aryl or alkyl-14hdibenzo[a,,j]xanthenesreaction under solvent-free conditions.compared to the classical 14-aryl or alkyl-14hdibenzo[a,j]xanthenesreaction conditions, this method consistentlyhas the advantage of excellent yields, mild reaction conditions, easeof workup, survival of different functional groups and short reactiontimes.
