A microwave-assisted fluorination method for 1,3-dicarbonyl compounds using Selectfluor® has been developed. 2-Monofluorinated products can be obtained in high yield in neutral reaction conditions with addition of 1 eq. of Selectfluor®. Treatment of 1,3-dicarbonyls with 3 eq. of Selectfluor® in the presence of tetrabutylammonium hydroxide (TBAH) as the base results in the formation of 2,2-difluorinated
用于使用的Selectfluor 1,3-二羰基化合物的微波辅助的氟化方法®已经研制成功。加入1eq。的2-单氟化产物可以在中性反应条件下高收率地获得。的Selectfluor的®。用3eq。处理1,3-二羰基。的的Selectfluor ®在氢氧化四丁基铵(TBAH)的存在下,在仅2,2-二氟化衍生物的形成基部的结果。
