olefins of the type XCH=CHY, where Y is an electron-withdrawing group and X is a good leaving group, can undergo nucleophilic vinylic substitution reactions by a single-step or a multistep addition–elimination mechanism, depending on the chemical structure of the olefin and the reaction ...

A wide range of selenium-containing reagents are known to undergo addition – elimination reactions under different reaction conditions. We report on selenium electrophiles, which are regenerated under the reaction conditions employed, and therefore only catalytic amounts of these reagents are necessary....

elimination reaction 使反应物分子失去两个基团(见基)或原子,从而提高其不饱和度的反应。 分类 按失去的两个基团在分子中的相对位置进行分类:①1,2-消除。或称β-消除。为处于相邻原子上的两个基团失去后在这两个原子之间生成π键(见共价键)的反应。两个原子都是碳原子时就发生成烯消除反应: ②1,1-消除。
