products from the neopentyl rearrangement on reaction with xenon difluoride. Neopentyl iodide performs a double rearrangement and yields a gem-difluoro product, 2,2-difluoro-3-methylbutane. Studies of the mechanism show that an alkene intermediate is involved in the double rearrangement process. Alkenes can be substituted as substrates in reaction with xenon difluoride–iodine to give gem-difluoro products
烷基碘化物与二氟化氙反应生成新戊基重排产物。新戊碘化物进行两次重排,并生成宝石-二氟产物2,2-二氟-3-甲基丁烷。机理研究表明,烯烃中间体参与了双重排过程。烯烃可以与二氟化氙-碘反应生成底二氟产物,从而代替其作为底物。13 C标签验证骨骼重排过程。
