Imine to ketone mechanism

Witryna10 kwi 2024 · Based on the above analysis, a plausible mechanism for imine synthesis is proposed (Figure 5D). The proposed catalytic mechanism is attributed to high concentrations of unpaired electrons in the carbon nanostructures, which reduce oxygen to form the superoxide radical anion (O2 •−).
