Reactivity of N-benzylidenebenzylamine (2a) over unmodified and acac-modified MnOx. a Mass-specific activities (mmol gcat−1 h−1) of MnOx and acac-MnOx in aerobic oxidation/ammoxidation of N-benzylidenebenzylamine (2a) under 0.3 MPa O2 at 90 °C. The mass-specific activity was measured at the reaction time of 1 h when the conversion is below 30%. b Selectivity-conversion correlation of N-benzylidenebenzylamine (2a) in aerobic oxidation of benzylamine under 0.3 MPa O2 at 90 °C. c Proposed mechanism. d Recyclability test results for selective synthesis of N-benzylidenebenzylamine (2a) by oxidation of benzylamine over acac modified MnOx. Reaction conditions: 1 mmol benzylamine, 0.1 mmol MnOx, acac/MnOx = 20 mol%, 5 mL CH3CN, 0.3 MPa O2, 90 °C, 14 h
