prepared and their stabilities toward oxidative elimination assessed. Simple competitive experiments demonstrate that electron-withdrawing substituents stabilize arylselenides toward oxidation, while electron-donating groups accelerate the oxidation process. In addition, ab initio and density functional calculations on model systems reveal that selenoxides are relatively insensitive to the nature of substituents
