铁(III)催化砜基α-碳负离子偶联成烯的非异构化证据
Evidence for Absence of Isomerization of Double Bond During Iron (III) catalyzed Sulfone α Carbanion Homocoupling
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.
