  the 4,4,4-trifluorobut-2-en-1-ol system under metal-free conditions to afford the corresponding saturated ketones in high to excellent chemical yields using such a convenient and easy-to-handle base as DBU at the toluene refluxing temperature, and utilization of the corresponding optically active substrates unambiguously demonstrated that this transformation proceeded in a highly stereoselective fashion

  遵循计算的期望，我们先前报道的有趣的4,4,4-三氟丁-2-yn-1-ols的1,3-质子移位已成功扩展到4,4,4-三氟丁-2-en-1在甲苯回流温度下使用方便且易于操作的碱（例如DBU），在无金属条件下使用-ol体系制得高至优异的化学收率的相应饱和酮，并明确利用了相应的光学活性底物，表明这种转变以高度立体选择性的方式进行。

  Treatment of β-fluoroalkylated-α,β-unsaturated ketones with 1.2 equiv. of various arylboronic acids in the presence of 5 mol% of [Rh(COD)2]BF4 and 6 mol% of (S)-BINAP in toluene/H2O (v/v = 4/1) at the reflux temperature for 3 h gave the corresponding Michael adducts in high yields with over 90% enantioselectivity. Though other electron-deficient alkenes, such as vinylsulfone and vinylphosphonate, were found to be much less reactive in the rhodium-catalyzed conjugate addition with arylboronic acids, the reaction of various arylstannanes toward such electron-deficient alkenes took place very smoothly to afford the corresponding adducts in high yields.

  在甲苯/H2O（v/v = 4/1）溶液中，加入 5 摩尔的[Rh(COD)2]BF4 和 6 摩尔的(S)-BINAP，在回流温度下，用 1.2 等份的各种芳基硼酸处理δ-氟烷基化-δ,δ-不饱和酮 3 小时，可得到相应的迈克尔加合物，产率高，对映选择性超过 90%。虽然其他缺电子烯类，如乙烯基砜和乙烯基膦酸，在铑催化的芳基硼酸共轭加成反应中反应性要差得多，但各种芳基锡烷与这些缺电子烯类的反应非常顺利，能以高产率得到相应的加合物。
