The stepwise construction of polyoxovanadate-based Zn-MOF nanoparticles with Lewis acid sites for the one-pot synthesis of N-heterocycles in air

The six-coordinated Zn 2+ in polyoxovanadate-based Zn-MOF ( 1 ) was tuned to a four-coordinated nanosized 2-NP (50 nm), which exhibited enhanced catalytic activity for the one-pot aerobic oxidation synthesis of benzimidazoles and quinazolinones.
