摘要

Method B. A solution of cycloheptene (960 mg, 10 mmol) in methanol (20 mL) was added in 5 min to a solution of oxone (6.15 g, 20 mmol of KHS06) in water (50 mL). Before the addition was started the pH was adjusted to 6 and it was monitored with a pH electrode and kept at this value during the entire reaction by dropwise addition of KOH (1 M in water). The reaction mixture was stirred for an additional 4 h and extracted with methylene
