Application of organoselenides in the Suzuki, Negishi, Sonogashira and Kumada cross-coupling reactions

Abstract

We reported herein the regio- and stereoselective palladium-catalyzed cross-coupling reactions of unsaturated organoselenides with Sonogashira, Suzuki, Negishi and Kumada partners. The reactions were in general carried out with Pd(PPh₃)₄ (10 mol%), in DMF at 80 °C to afford the cross-coupling products in good yields. This strategy tolerated a wide range of substrates, such as alkynyl, vinyl, aryl and heteroaryl selenides with a variety of sensitive functional groups and gave the cross-coupling products in good yields.
