Fig. 4: TBADT photocatalyzed hydrogenation of unsaturated organic compounds with prenol as the hydrogen source.

Reaction conditions: substrate a alkenes, b diazo compounds, c, d alkynes (0.1 mmol), prenol (5 equiv.), CH3CN (2 mL), TBADT (5 mol%), 390 nm LEDs (40 W), 24 h, room temperature; yields are isolated yields. *6 h reaction time. †400 nm LEDs (40 W). ‡Reaction at 70 °C. #Yields determined from crude 1H NMR spectra using 1,3,5-trimethoxybenzene as the internal standard.
