Abstract
|
In the current paper, we successfully developed and used metal−organic frameworks (MOFs) based on MIL-101(Cr)- NH2 with phosphorus acid functional groups MIL-101(Cr)- N(CH2PO3H2)2. The synthesized metal−organic frameworks (MOFs) as a multi-functional heterogeneous and nanoporous catalyst were used for the synthesis of N-amino-2-pyridone and pyrano [2,3-c]pyrazole derivatives via reaction of ethyl cyanoacetate or ethyl acetoacetate, hydrazine hydrate, malononitrile, and various aldehydes. The final step of the reaction mechanism was preceded by a cooperative vinylogous anomeric-based oxidation. Recycle and reusability of the described catalyst MIL-101(Cr)- N(CH2PO3H2)2 were also investigated.
