Amine functionalized MCM-41: an efficient heterogeneous recyclable catalyst for the synthesis of quinazoline-2,4(1H,3H)-diones from carbon dioxide and 2-aminobenzonitriles in water

Abstract

Covalently linked amine functionalized MCM-41 was investigated as an efficient catalyst for the synthesis of various quinazoline-2,4(1<italic>H</italic>,3<italic>H</italic>)-dione derivatives from 2-aminobenzonitriles and carbon dioxide in water.
