Room-temperature fluorination of pentane-2,4-dione with CsSO4F gave 3-fluoro and 1,3-difluoro derivatives, while 5,5-difluorobarbituric acid was formed in high yield in a 2 h reaction at 100 °C; 1,3-dimethyluracil was converted in methanol via cis- and trans-5-fluoro-6-methoxy derivatives into 5-fluoro-1,3-dimethyluracil in high yield and uridine into 5-fluorouridine.
用CsSO 4 F在室温下氟化戊烷-2,4-二酮可得到3-氟和1,3-二氟衍生物,而在100°C的2 h反应中高产率形成5,5-二氟巴比妥酸;1,3-二甲基尿嘧啶在甲醇中通过顺式和反式-5-氟-6-甲氧基衍生物高产率转化为5-氟-1,3-二甲基尿嘧啶,尿苷转化为5-氟尿苷。
