Fig. 7: Photocatalyzed reduction of dinitro substrates using different reductants.

Isolated yields are reported. Standard conditions for cyclic azo product conversion were as follows: 1.0 mol% H_F (0.50 μmol), substrate (0.05 mmol) and tripropylamine (1.20 mmol) under light irradiation for 10 h. Standard conditions for diamino product conversion were as follows: 1.0 mol % of H_F (0.50 μmol), substrate (0.05 mmol) and Na₂S (1.20 mmol) under light irradiation for 2 h.
