Supporting information for this article is given via a link at the end of the document. By intercepting the acylpalladium species with C=Nbond of azaarenes or imines other than free amines or alcohols, the difunctionalization of C=Nbond was established via palladium‐catalyzed carbonylation/nucleophilic addition sequence. This method is compatible with a diverse range of azaarenes and imines and allows

The synthesis of 2,3-dihydroquinazoline-4(1H)-one and dihydroisoindolo[2,1-a]quinazoline-5,11-dione derivatives in the presence of imidazolium ionic liquid sulfonic acid functionalized SBA-15: a novel feature of SBA-15
3-dihydroquinazoline-4(1H)-one and dihydroisoindolo[2,1-a]quinazoline-5,11-dione derivatives via three-component reaction between isatoic anhydride, amines and aromatic aldehydes at 50 °C in ethanol and water mixture as solvent. We found the synthetic imidazolium ionic liquid sulfonicacid functionalized SBA-15 as a convenient catalyst for this methodology. The catalyst performs the reaction in mild reaction conditions
