A convenient and efficient method for preparing 3,3,3-trifluoropropanoic acid (1) is reported. The starting material is 1-chloro-3,3,3-trifluoropropene (2) that can be easily transformed into 3,3,3-trifluoropropanal dimethyl acetal (4) on treatment with methanol and KOH followed by acid-catalyzed addition of methanol. Direct transformation of 4 into 1 was efficiently achieved with 30% aqueous hydrogen
报道了一种方便有效的制备3,3,3-三氟丙酸(1)的方法。起始原料为1-氯-3,3,3-三氟丙烯(2),经甲醇和KOH处理,然后酸催化加入甲醇,可以轻松转化为3,3,3-三氟丙二甲基缩醛(4)。 。在FeCl 3(0.025当量)和盐酸(0.5当量)存在下,用30%的过氧化氢水溶液(4.0当量)有效地将4直接转化为1。
