a Investigations of reducing catalysts loading. Reactions were performed on 0.5 mmol scale in a 4 mL glass vial for 30 min. The yields were determined by GC-FID with dodecane as the internal standard. a2 mmol scale. b Scale-up experiments of product 4 with images showing the reaction mixture before and after completion. c Scale-up experiments of product 70 with images showing the reaction mixture before and after completion. d Other scale-up experiments with 0.01% 4CzIPN as a photo catalyst.
