(4-Hydroxypiperidin-1-yl)tetra- and -octafluorochalcones reacted with phenylhydrazine in acetic acid to give mixtures of polyfluoro-1,3,5-triaryl-4,5-dihydro-1H-pyrazoles and their O-acetyl derivatives. Analogous reactions in ethanol afforded in satisfactory yields 1-[4-(1,3-diaryl-4,5-dihydro-1H-pyrazol-5-yl)-2,3,5,6-tetrafluorophenyl]piperidin-4-ols which were treated with acryloyl chloride to obtain the corresponding acrylates that are promising as monomers for the preparation of fluorescent films.
(4-羟基哌啶-1-基)四氟和八氟查尔酮在乙酸中与苯肼反应,生成多氟代-1,3,5-三芳基-4,5-二氢-1H-吡咯和它们的O-乙酸衍生物的混合物。在乙醇中类似的反应以令人满意的产率提供了[4-(1,3-二芳基-4,5-二氢-1H-吡咯-5-基)-2,3,5,6-四氟苯基]哌啶-4-醇,这些化合物与丙烯酰氯反应得到相应的丙烯酸酯,作为制备荧光膜的潜在单体。
