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.

AbstractSymmetrical and unsymmetrical 3,3-di(aryl)indolin-2-ones have been synthesized by nano-SiO2 as green, heterogeneous, and reusable catalyst under solvent-free conditions at room temperature via magnetic stirring and grinding methods. A plausible mechanism of condensation has also been presented.
