Fig. 5: Substrate scope for the synthesis of amides.

Reaction conditions: substrate (0.25 mmol), Co-NC-900 (5.5 mol%), 3 Å molecular sieve (100 mg), DMSO (1 mL), 0.5 MPa NH3, 0.5 MPa O2. The detailed experimental procedures are provided in the Supporting Information. Yield was determined by GC analysis using biphenyl as internal standard and the product was confirmed by GC-MS. aCo-NC-900 (11 mol%), 25-28 wt% aq. NH3 (155 μL), 170 °C, 48 h.
