Xenon difluoride and caesium fluoroxysulphate reacted in methylene chloride or acetonitrile with various enol acetates, diketones, and ketones, yielding mainly α-fluoro ketones, the course of the reaction depending on the reagent and the structure of the organic molecule. Enol acetates from cycloakanones were converted with caesium fluoroxysulphate to α-fluorocycloalkanones in high yield. Xenon difluoride
二氟化氙和氟代硫酸铯在二氯甲烷或乙腈中与各种烯醇乙酸酯,二酮和酮反应,主要生成α-氟代酮,反应过程取决于试剂和有机分子的结构。用氟代硫酸铯将来自环akanones的烯醇乙酸酯高产率地转化为α-氟代环烷酮。二氟化氙和氟代硫酸铯将苯并环烷酮-1的烯醇乙酸酯转化为α-氟苯并环烷酮,而苯并环烷酮-2的烯醇乙酸酯的反应性取决于所使用的试剂。用XeF 2和CsSO 4转化1,3-二苯基丙烷-1,3-二酮及其烯醇乙酸酯F为单和二氟取代的产物,反应过程取决于试剂。氟化二氙将1-茚满酮转化为重排的2,2-二氟苯并烷,而氟代硫酸铯与2-茚满酮反应生成1-氟-2-茚满酮。
