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 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
在这篇通讯中,我们报告说我们的试剂 PhSeZnCl 可以方便地用于影响不饱和酮和缺电子炔烃的迈克尔加成反应,分别导致合成有用的 β-硒代衍生物和乙烯基硒化物。反应在室温下在 THF 中以及在“水上”条件下进行。当加成发生在三键上时,观察到良好的立体选择性,并且反应在水悬浮液中显示出速率加速。
