Microwave accelerated synthesis of enol carbamates using nano metal-organic frameworksas catalyst

Enol carbamates were formed through oxidative coupling reaction of formamides and β-dicarbonylderivatives under microwave irradiation. We used metal-organic framework Cu2(BDC)2(DABCO) (BDC=1,4-benzenedicarboxylate, DABCO= 1,4-diazabicyclo[2.2.2]octane) as heterogeneous catalyst. This catalyst could befacilely separated from the reaction mixture, could be recovered and reused several times without significantdegradation in catalytic activity.
