  摘要：

  AbstractHerein we demonstrate a tricyclohexylphosphine‐catalyzed cycloaddition of (E)‐ or (Z)‐alkyl 5‐substituted phenylpent‐2‐en‐4‐ynoates with [60]fullerene to give cyclopentenofullerenes in good to excellent yields, through initial chemo‐ and regioselective 1,4‐addition of phosphines at the β‐carbon of the enyne substrates. The nucleophilic addition pattern of P(cHx)3 is found to be different from that of Gilman or Grignard reagents toward the studied enynes. The resulting cyclopentenofullerenes, characterized with spectrometric methods and single crystal X‐ray diffraction analysis, exhibit comparable or higher LUMO energy levels than a typical n‐type material, [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM).magnified image

  acetal with tetrahalomethane or trihalomethane at room temperature in the presence of a catalytic amount of Et3B provides 3,3-dihaloacrylate or (E)-3-haloacrylate, respectively. On the other hand, a reaction at −23 °C mainly gives 3,3,3-trihalopropanoate or 3,3-dihalopropanoate.

  在催化量的 Et3B 存在下，在室温下用四卤甲烷或三卤甲烷处理乙烯酮甲硅烷基缩醛，分别提供 3,3-二卤代丙烯酸酯或 (E)-3-卤代丙烯酸酯。另一方面，-23 °C 的反应主要产生 3,3,3-三卤代丙酸酯或 3,3-二卤代丙酸酯。
