  Hf(OTf)4 was identified as a highly potent catalyst (0.1–0.5 mol%) for three-component Mannich reaction under solvent-free conditions. Hf(OTf)4-catalyzed Mannich reaction exhibited excellent regioselectivity and diastereoselectivity when alkyl ketones were employed as substrates. 1H NMR tracing of the H/D exchange reaction of ketones in MeOH-d4 indicated that Hf(OTf)4 could significantly promote the

  Hf(OTf)4 被确定为在无溶剂条件下进行三组分曼尼希反应的高效催化剂（0.1-0.5 mol%）。当使用烷基酮作为底物时，Hf(OTf)4 催化的曼尼希反应表现出优异的区域选择性和非对映选择性。酮在 MeOH-d4 中的 H/D 交换反应的 1H NMR 示踪表明 Hf(OTf)4 可以显着促进酮-烯醇互变异构化，从而有助于加快反应速率。

  The remarkable activation effect of alcohol solvent on kinetically inert titanocene dichloride was found to promote rapid three-component Mannich reactions. NMR and ESI-MS analyses as well as a control experiment of catalytic active species elucidated that the coordination of MeOH to the titanocene moiety unleashed the Lewis acid [Cp2Ti(OMe)2] and Brønsted acid HCl, which led to the enhanced catalytic

  发现醇溶剂对动力学惰性二茂钛二氯化物的显着活化作用促进了快速的三组分曼尼希反应。NMR和ESI-MS分析以及催化活性物种的对照实验表明，MeOH与二茂钛部分的配位释放出路易斯酸[Cp 2 Ti（OMe）2 ]和布朗斯台德HCl，从而增强了催化作用Cp 2 TiCl 2的活性。

  A new binary acid system featuring an air stable organometallic precursor, titanocene dichloride and a simple Brønsted acid–base compound, was developed. The new catalyst system allowed for mild and highly efficient direct three-component Mannich reactions of both aryl ketones and alkyl ketones, in particular, acetone and its derivatives with excellent yields. Mechanistic study elucidated the dramatic synergistic effect of the new binary acid system.

  Rare earth (III) perfluorooctane sulfonates (RE(OPf)3) catalyze the three-component Mannich-type reactions of different ketones with various aromatic aldehydes and aromatic amines in fluorous media to give various β-arylamino ketones in good yields. By simple separation of the fluorous phase containing only catalyst, reaction can be repeated several times.
