"On-water" Michael-type addition reactions promoted by PhSeZnCl

experimental part, p. 1848 - 1851 (2011/05/05)
In this communication we report that our reagent PhSeZnCl can be conveniently used to effect Michael addition like reactions of unsaturated ketones and electron-deficient alkynes, leading to synthetically useful β-seleno derivativesand vinyl selenides, respectively. The reactions are effected at room temperature in THF as well as under "on water" conditions. When the addition occurs on a triple bond, good stereoselectivity is observed, and the reaction shows a rate acceleration in water suspension. Copyright
Selenium in Organic Synthesis: A Novel Route to 1-Phenylselenobutadienes and 1,4-Dicarbonyl Compounds
Comasseto, J. V.,Brandt, C. A.
, p. 146 - 149 (2007/10/02)
Two approaches to 1-phenylseleno-1,3-butadienes 5 are reported, via phenylselenoalkenylidene phosphoranes and phenylselenoalkenals, respectively. 1,4-Dicarbonyl compounds are prepared from the 1-phenylselenobutadienes or from the phenylselenoalkenals.
