  1. *The reaction solvent was 5 mL acetonitrile + 10 mL water, 0.1 M TMABr, and 0.05 M reaction substrate at a reaction potential of 1.8 V vs. RHE and a controlled reaction charge of 150 ~ 200 C. Quantitative analysis by GC-MS, NMR, and GC. Yield, selectivity, and Faraday efficiencies were calculated in a similar manner as for cyclohexene.
