Abstract

Abstract A new procedure was proposed for activation of areneselenenamides with phosphorus (V) and sulfur (IV) oxyhalides. According to the 1 H, 13 C, and 31 P NMR data, areneselenenamide reacts with phosphorus oxyhalide to form intermediate adduct in which the phosphorus atom is coordinated at the selenium. Areneselenenamides activated by phosphorus (V) oxyhalides react with alkenes (norbornene and norbornadiene) with high ...
