  1. The yields in Table 2 are the isolated yields; “Con.” represent as “Conversion”; The “Pro. x” represents “Product x”, and “x” is the number of the compound synthesized in this manuscript.
  2. aReaction conditions: substrate A (0.5 mmol), ethanol (10 mL), the Zn-N4-C catalyst (20 mg), N2 (10 bar), 180 °C and 12 h.
  3. bBenzyl alcohol (5 mmol), and hexane (10 mL) were used.
