TL;DR: KAl(SO4)2·12H2O was found to catalyze efficiently a one-pot three-component cyclocondensation of isatoic anhydride and primary amines or ammonia sources such as NH4 2CO3, NH4OAc and NH4Cl with aromatic aldehydes under mild conditions to afford the corresponding mono- and disubstituted 2,3-dihydroquinazolin-4(1H)-ones in good yields as mentioned in this paper.

TL;DR: In this article, a highly selective synthesis of 2-aryl-1-arylmethyl-1H-1,3-benzimidazoles from the reaction of o-phenylenediamines and aromatic aldehydes in the presence of silica sulfuric acid is reported.

TL;DR: In this paper, the effects of different ILs on the yield of reactions were investigated, and the use of ionic liquids offer improvements for the synthesis of title compounds with regard to the yield, simplicity in operation, short reaction times and green aspects by avoiding toxic catalyst and organic solvents.
