Reaction of thymines with Na2S2O8 in water resulted in selective oxidation of the methyl group at 5-position of thymines. Oxidation of thymines with Na2S2O8 in hydrochloric acid gave 5-chloro-6-hydroxy-5,6-dihydrothymines and in acetic acid containing NaCl gave 6-acetoxy-5-chloro-5,6-dihydrothymines which were converted to 6-alkoxy-5-chloro-5,6-dihydrothymines with alcohols. The reaction of uracils also gave similar products together with 5-chlorouracils.
胸腺嘧啶与Na2S2O8在水中的反应导致了胸腺嘧啶5位甲基基团的选择性氧化。在盐酸中用Na2S2O8氧化胸腺嘧啶生成5-氯-6-羟基-5,6-二氢胸腺嘧啶,而在含NaCl的醋酸中则生成6-乙氧基-5-氯-5,6-二氢胸腺嘧啶,这些化合物可以与醇转化为6-烷氧基-5-氯-5,6-二氢胸腺嘧啶。尿嘧啶的反应也产生了类似的产物,同时伴随着5-氯尿嘧啶的生成。
