铁(III)催化砜基α-碳负离子偶联成烯的非异构化证据

Abstract

以β，β-二氘代砜为反应物进行铁（II）催化的砜基α-碳负离子的去砜基偶联烯烃化反应，用1HnMr测定生成的氘代烯烃直接证明该反应体系中未发生双键迁移.

By using β,β dideuterosulfone as starting material, the iron (III) catalyzed α sulfonylcarbanion desulfonitive homocoupling to form the corresponding deuteroalkene was demonstrated to be absence of double bond migration.
