Fluoroalkyl acetic acids were converted to their corresponding carbonyl chlorides , which was then reacted with o - amino benzaldehyde and ammonia gas to give 3 - ( 1 - iminofluoroalkyl ) - 1h - qunolin - 2 - ones in moderate yields 摘要用2 -氟烷基乙酸为初始原料,用氯化亚砜或五氯化磷将其转化为相应的酰氯,后者在室温与邻胺基苯甲醛缩合,通入氨气回流反应得到3 - ( 1 -亚胺基氟烷基) 1h -喹啉2 -酮类化合物,产率中等。
