• 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

  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.

  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%）。

  containing a rigid dihydroanthracenyl skeleton are suitable precursors for both organometallic and organo-based catalysts. A Rh–carbene complex and the triazolium salt efficiently catalyzed the 1,4-additions of C- and heterodonor reagents to α,β-unsaturated carbonyl substrates, respectively.

  The 1,4-conjugate addition of primary, secondary and aromatic amines, thiols, and carbamate to α,β-unsaturated compounds mediated by a catalytic amount (0.5 mol%) of RuCl 3 in poly(ethylene glycol) (PEG) provides the desired β-substituted carbonyls in high yields. In particular, we found that primary aliphatic and aromatic amines produced the single adducts as the sole products in very high yields

  在聚乙二醇 (PEG) 中催化量 (0.5 mol%) 的 RuCl 3 介导的伯胺、仲胺和芳香胺、硫醇和氨基甲酸酯与 α,β-不饱和化合物的 1,4-共轭加成提供了以高产率获得所需的β-取代羰基。特别是，我们发现脂肪族伯胺和芳香族伯胺与 RuCl 3 -PEG 以非常高的产率产生单一的加合物作为唯一的产物。RuCl 3 -PEG 很容易通过溶剂沉淀进行回收，具有高效的可回收性，高产率证明了这一点。其对水分和氧气的低敏感性、对不同官能团的高耐受性和高效的可回收性使RuCl 3 -PEG适用于实验室和工业规模的β-取代羰基化合物的合成。

  Aza-Michael reactions of enones with carbamates took efficiently in the presence of a catalytic amount of quaternary ammonium salts and BF 3 .OEt 2 to afford the total products in high yields. The new catalytic system was also efficient in the aza-Michael reaction of chalcone, which was difficult to react with carbamates by transition metal salts catalysts.

  Aza-Michael reactions of enones with carbamates took place efficiently in the presence of a catalytic amount of phosphine and TMSCI to afford the total products in high yields. The new catalytic system was also efficient in the aza-Michael reaction of chalcone, which was difficult to react with carbamates by transition metal salts catalysts. (C) 2004 Elsevier Ltd.
