Nano‐MgO/ZrO2 is prepared and used as catalyst for cross‐aldol condensation, Cbz‐protection of amines, reduction of aromatic nitro compounds and the synthesis of 1,5‐benzodiazepines.
The synthesis of quinazoline-2,4(1H,3H)-diones from carbon dioxide and 2-aminobenzonitriles using MgO/ZrO 2 as a novel and efficient heterogeneous base catalyst is reported. The synthesized MgO/ZrO 2 catalyst was characterized by XRD, FTIR and its basic properties were measured using CO 2 temperature programed desorption analysis. The effects of various reaction parameters were investigated in detail. A wide variety of aromatic aminobenzonitriles and five member N-heterocyclic carbonitriles were synthesized using this protocol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
