  Acidic-functionalized ionic liquid as an efficient, green and reusable catalyst for hetero-Michael addition of nitrogen, sulfur and oxygen nucleophiles to α,β-unsaturated ketones

  摘要：

  一系列酸性功能化的离子液体被合成并应用于无溶剂条件下氮、硫和氧亲核试剂对α,β-不饱和酮的加成反应。值得注意的是，1-甲基咪唑对甲苯磺酸（[Hmim]OTs）被发现是最有效的催化剂，并能实现“均相催化，两相分离”。此外，该催化体系具有广泛的底物适用范围，并且在室温下能够获得良好至极佳的产率（高达99%）。

  A series of acidic-functionalized ionic liquids were synthesized and applied to the hetero-Michael addition of nitrogen, sulfur and oxygen nucleophiles to α,β-unsaturated ketones under solvent-free conditions. Notably, 1-methylimidazoliump-toluenesulfonic ([Hmim]OTs) was found to be the most efficient catalyst and could realize “homogeneous catalysis, two-phase separation”. Additionally, the catalytic system has wide substrate scope and good to excellent yields (up to 99%) could be obtained at room temperature.

  A method for synthesizing β-sulfanyl ketones via a tandem rearrangement and conjugate addition reaction has been developed. This methodology provides access to a range of β-sulfanyl ketones through the rearrangement of propargyl alcohols to the corresponding enones followed by the conjugate addition of unactivated thiols. The one-pot, tandem transformation is catalyzed by ReOCl3(OPPh3)(S(CH3)2) affording

  已经开发了通过串联重排和共轭加成反应合成β-硫烷基酮的方法。通过将炔丙醇重排成相应的烯酮，然后共轭添加未活化的硫醇，该方法学提供了一系列β-硫烷基酮的途径。通过ReOCl 3（OPPh 3）（S（CH 3）2）催化一锅串联转化，可提供高收率的芳基和烷基β-硫烷基酮。

  found to be an efficient bifunctional catalyst for the 1,4-addition of thiols to α,β-unsaturated ketones. The addition of thiophenol derivatives and alkyl thiols proceeds under mild reaction conditions without pre-activation of the thiol or exogenous base. Reactions of aryl, alkyl, and cyclic enones produce the corresponding β-sulfanyl ketones in good to excellent yield.
