过硫酸盐是一类常用的氧化剂,它与各种金属离子,如 Cu~(2+),Fe~(3+)等,组成的氧化体系能对许多有机化合物进行氧化,其中有些已发展成为有价值的合成方法。近年来,人们观察到苯环上的甲基在不同反应介质中可以方便地被 S_2O_8~(2-)-Cu~(2+)体系氧化,而生成相应的乙酸苄酯或苯甲醛。这个氧化过程通常被认为是经过单电子转移历程进行的。如果用特定的 S_2O_8~(2-)-Cu(2+)体系(ArH:
Persulfate is a kind of commonly used oxidant. It oxidizes many organic compounds with various metal ions, such as Cu 2+ and Fe 3+. Some of them have been oxidized to Valuable method of synthesis. In recent years, it has been observed that the methyl groups on the benzene ring can be easily oxidized by the S 2 O 8 2- (2 -) - Cu 2+ system in different reaction media to generate the corresponding benzyl acetate or benzaldehyde. This oxidation process is generally considered to be carried out through a single electron transfer process. If a specific S_2O_8 ~ (2 -) - Cu (2+) system (ArH:
