a
Reaction conditions: cat. (0.0017 mmol), molar ratio of cat. : imidazole : MePhS : H2O2: is 1 : 100 : 300 : 1500, solvent: EtOH (1 mL), stirred at r.t., potential: 60 V, and time: 90 s.
b
GC yield based on the starting reactant methyl phenyl sulfide. Methyl phenyl sulfoxide is the sole product.
c
Reaction conditions: cat. (0.0017 mmol), molar ratio of cat. : imidazole : cyclooctene : H2O2 is 1 : 100 : 150 : 750, solvent: EtOH (1 mL), stirred at r.t., potential: 60 V, and time: 90 s.
d
GC yield based on the starting reactant cyclooctene. Cyclooctene oxide is the sole product.
