Hydrates of trifluoropyruvamides are readily obtained from isocyanides and trifluoroacetic anhydride. Under catalysis with secondary amines, these hydrates were successfully reacted with various methylketones to form fluorinated aldol type compounds. The effect of the amine is discussed as well as Henry type additions with nitromethane.
三氟丙酮酰胺的水合物很容易从异氰化物和三氟乙酸酐获得。在仲胺催化下,这些水合物成功地与各种甲基酮反应形成氟化的醛醇型化合物。讨论了胺的作用以及与硝基甲烷的亨利型加成反应。
