Rhodium-catalyzed highly regio- and stereoselective hydroselenation of internal alkynes bearing an electron-withdrawing group took place to give (E)-vinyl selenides in good yields. The excellent syn stereoselectivity of this rhodium-catalyzed hydroselenation is of great importance in terms of complementing the previously reported hydroselenation of alkynes.
铑催化了带有吸电子基团的内部炔烃的高度区域选择性和立体选择性加氢硒化反应,从而以高收率得到(E)-乙烯基硒化物。就补充先前报道的炔烃的加氢精制而言,这种铑催化的加氢精制的优异的顺式立体选择性非常重要。
