Rhodium-Catalyzed Highly Stereoselective Hydroselenation of Internal Alkynes Bearing an Electron-withdrawing Group

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.
