在CH~3CN中,β-氟烷基烯基碘与硫酚负离子能发生消除-加成反应生成碘被取代的产物;硫醇负离子及氧负离子对β-氟烷基烯基碘进攻则生成消除产物氟烷基炔烃。

In CH~3CN, fluoroalkyl vinyl iodides react with aryl thiolate ions to give the iodine-substituted products via an elimination-addition mechanism. However, treatment of fluoroalkyl vinyl iodides with alkoxide or alkyl thiolate ions affords only fluoroalkyl alkynes through a simple elimination process.
