Phosphoric acid alkyl diphenyl esters were prepared by reacting diphenyl phosphoryl chloride with alcohols in the presence of amines, and then subjected to fluorinative hydrolysis with Bu4 NF to give phosphorofluoridic acid ammonium salt monoesters in moderate to high yields. The salts were converted to the corresponding acids by treatment with Amberlyst 15. The NMR properties of a series of organophosphorus
在胺类存在下,二苯基磷酰氯与醇类反应制备磷酸烷基二苯酯,然后用 Bu4 NF 进行氟化水解,以中等至高产率得到氟代磷酸铵盐单酯。通过用Amberlyst 15 处理将盐转化为相应的酸。展示了一系列有机磷化合物的NMR 特性。测试了酸对α-溴丁酸和3-己炔-2-醇缩合反应的催化活性。© 2011 Wiley Periodicals, Inc. 杂原子化学 22:417–425, 2011; 在 wileyonlinelibrary.com 上在线查看这篇文章。DOI 10.1002/hc.20700
