The direct fluorination reaction of acetophenone using iodosylarenes and TEA·5HF was conducted under mild conditions except for use of a HF reagent. The fluorination reaction was applied to acetophenone derivatives, acetonaphthones, benzyl phenyl ketone, propiophenone, butyrophenone, 1-indanone, and phenacyl chloride, giving selectively the corresponding α-fluoroketone derivatives in good yields.
除了使用HF试剂以外,在温和的条件下,使用碘代芳烃和TEA·5HF进行苯乙酮的直接氟化反应。将氟化反应应用于苯乙酮衍生物,对乙酰苯甲酮,苄基苯基酮,丙苯酮,丁苯酮,1-茚满酮和苯甲酰氯,以高收率选择性地得到相应的α-氟代酮衍生物。
