| 摘 要： | 由氟烷基亚磺酰氯制备得到氟烷基联烯砜，并对其和胺及水的加成反应进行了研究。室温下，二级胺可以和联烯砜反应得到相应的烯胺加成产物，该产物在甲苯中加热回流可重排得到共轭的烯胺。二乙胺在对γ－甲基－γ－乙基氟烷基联烯砜进行加成时，反应有很好的立体选择性。在回流的乙腈中水也可与氟烷基联烯砜发生类似的加成反应。

| Abstract: | Preparation of allenyl perfluoroalkyl sulfones from perfluoroalkyl sulfinyl chlorides and their reactions with secondary amines and water were studied. At room temperature secondary amines reacted readily with allenyl perfluoroalkyl sulfones to give the corresponding enamine adducts, which underwent rearrangement to afford conjugate enamines in refluxing toluene. Good diastereoslectivities were observed in the addition of diethylamine to 7-ethyl-7-methylallenyl perfluoroalkyl sulfones. In refluxing acetonitrile, water could also undergo the similar addition with allenyl perfluoroalkyl sulfones. |
