摘要：
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 beta-seleno derivatives and 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.
