Alkali α-MnO2/NaxMnO2 collaboratively catalyzed ammoxidation–Pinner tandem reaction of aldehydes

A bifunctional manganese oxide catalyst with an interface binding a redox phase (α-MnO₂) and a basic phase (Na_xMnO₂) was reported for the ammoxidation–Pinner tandem reaction to synthesize imidates in 58–96% yields from aldehydes.
