摘　　要：报导了芳族二硒醚在SmI_2作用下,Se—Se键还原断裂成硒负离子。再与α,β-不饱和酯(腈)发生Michael加成反应,得到β-硒代酯(腈)。The Se-Se bond in diphenyl diselenide were reduced by Samarium (Ⅱ) diiodide to produce samarium phenylselenolate. The new selenolate anion reacted with α, β-unsaturated esters or α, β-unsaturated nitriles to give β-seleno esters and β-seleno nitrfiles, respecively.
