The apparent electrophilic fluorination of 1,3-dicarbonyl compounds using Et3N·3HF as a nucleophilic fluoride source is reported. This reaction requires PhI(OAc)2 as oxidant and can be conducted safely in standard laboratory glassware. Alternative selectivity compared to Selectfluor was observed in some cases. This approach may reduce our reliance on difficult-to-handle fluorine gas and expensive electrophilic
报道了使用 Et3N·3HF 作为亲核氟化物源的 1,3-二羰基化合物的表观亲电氟化。该反应需要 PhI(OAc)2 作为氧化剂,可以在标准实验室玻璃器皿中安全进行。在某些情况下,观察到了与 Selectfluor 相比的替代选择性。这种方法可以减少我们对难以处理的氟气和源自元素氟的昂贵亲电子氟化剂的依赖。介绍了与活性氟化物质和氟化物/乙酸盐交换相关的机理分析。
