a CV of related compounds in the catalytic system. b CV of 1a in the absence or in the presence of a Lewis acid catalyst. c CV of 2a in the absence or in the presence of a Lewis acid catalyst. d Profile of a current-switched on-off experiment. e Kinetic studies to investigate the racemic background reaction. f Investigation of the catalyst loading. The reaction condition with silver oxide as a chemical oxidant instead of an electrical input: reactions were carried out using racemic benzoxazolyl acetate 1a (0.1 mmol), allenylmethylsilane 2a (0.30 mmol), nBu4NPF6 (0.15 mmol), quinuclidine (0.05 mmol), Ni(OAc)2·4H2O/L9 (0.5–10 mol%), Cp2Fe (0.5-10 mol%), Ag2O (0.30 mmol), and DCM/TFE = 2:1 (3 mL) at 25 °C. g Control experiments. h Radical clock experiment. i Proposed catalytic cycle.
