^at_p: the photochemical reaction time; t_d: the time exposure to air in the absence of light. ^bConversion rate of nitro-compounds. ^cSelectivity to azoxy-compounds. ^dSelectivity to imines; ^ePerformed in a PA solution due to its poor solubility in an aqueous solution (2 mL of PA, 80 mW cm⁻²). Photochemical reaction conditions: deionized water (1.5 mL), amine (0.5 mL), nitro compound (0.04 mmol), 40 °C, 1 atm Ar, purple LED light (200 mW cm⁻²).
