Catalytic Performances

Ionic liquid [DMEA][HSO4] was found to be an efficient and reusable catalyst for the one-pot synthesis of 14-aryl-14H-dibenzo[a,j]xanthenes under solvent-free conditions. The excellent catalytic performances are believed to come from the synergetic effect of the cation and anion of the ionic liquid.
