Abstract Direct fluorination of 1,3-dicarbonyl compounds including 1,3-diketones, 3-oxo esters, and 3-oxoamides was conducted using aqueous hydrofluoric acid with the aid of iodosylarenes, giving the corresponding 2-fluorinated products in good to high yields. Among the used iodosylarenes, o-iodosyltoluene was found to be the most effective, and the yield of 2-fluorinated products was improved. Direct
摘要 在碘代芳烃的帮助下,使用氢氟酸水溶液对包括1,3-二酮,3-氧代酯和3-氧代酰胺在内的1,3-二羰基化合物进行直接氟化,以高至高收率得到相应的2-氟化产物。在所使用的碘代芳烃中,邻-碘代甲苯基被认为是最有效的,并且2-氟代产物的产率得以提高。 在碘代芳烃的帮助下,使用氢氟酸水溶液对包括1,3-二酮,3-氧代酯和3-氧代酰胺在内的1,3-二羰基化合物进行直接氟化,以高至高收率得到相应的2-氟化产物。在所使用的碘代芳烃中,邻-碘代甲苯基被认为是最有效的,并且2-氟代产物的产率得以提高。
