  摘要：

  描述了一种温和而有效的方法，该方法使用催化量的CAN以优异的产品收率将硫醇和苯硒酚的1,4-加成成各种α，β-不饱和酮。这种廉价，无毒且容易获得的催化硝酸铈（IV）铵体系可在无溶剂条件下有效催化硫醇衍生物与各种α，β-不饱和酮之间的共轭加成反应。提出了一种可能的机制，即CAN在自由基链加成反应中作为促进剂以及在共轭加成过程中的催化作用。

• The iron(III) chloride-mediated 1,4-addition of mercaptans to α,β-unsaturated ketones and esters under solvent free conditions

  The 1,4-addition of various thiols to alpha,beta-unsaturated ketones was completed rapidly in the presence of a catalytic amount (2-3 mol %) of anhydrous iron(III) chloride under solvent free conditions and an air atmosphere. Anhydrous iron(III) chloride is more active than that of other ferric salts. With more reactive and/or less steric reagents (1a-c and/or 2a-2c), expeditious conditions (short reaction times at room temperature) could be employed. With less reactive and/or steric reagents (1d-g and/or 2d-e), a slight increase in reaction time was required, but high yields were obtained. The FeCl3 catalyst causes preferential interactions with alpha,beta-unsaturated ketones present in the reaction. (c) 2006 Published by Elsevier Ltd.

  A defined NHC-Fe-S complex proved to be an efficient catalyst for the selective hydrosulfenylation of alpha/beta-unsaturated ketones or vinylnitriles. A wide range of different aliphatic thiols were transferred in this atom-economic reaction into the corresponding thioethers. Mild reaction conditions, equimolar amounts of substrates, low catalyst loadings, and mild reaction conditions are characteristic for this transformation.
• Organic reaction in water. Part 2: Michael addition in water without phase transfer agents

  The Michael additions of dicarbonyl compounds, nitroalkanes, and thiols to 2-cyclohexen-1-one can be accomplished in water without phase transfer agents. The reaction is extremely sensitive to the pH of the reaction media, and therefore, the methodology can be optimized with the control of this variable. The best pH depends on the used nucleophile.

  Abstractmagnified imageA pronounced catalytic effect of sodium dodecyl sulfate (SDS) was observed on thein situproduction ofS‐alkylisothiouronium saltsviathe reaction of primary, allyl and benzyl halides with thiourea in SDS droplets .Hydrolysis of the generatedS‐alkylisothiouronium salts in the palisade layer of the droplets produces the corresponding thiol moieties which are immediately added to the electron‐deficient olefins that are present in the micellar core to produce the thia‐Michael adducts. The entire route is an almost odorless process. The yields of the products are good to excellent and the method is applicable to large‐scale operation without any problem.
