Reaction of perfluoro-3,4-dimethylhex-3-ene (1) with amine gives products which arise from nucleophilic attack directly on (1) but also products derived from attack on isomers of (1), i.e. perfluoro-3,4-dimethylhex-2-ene (2) and perfluoro-3-methylene-4-methylhexane (3), promoted by fluoride ion which is generated during reaction. The products obtained depend critically on the steric requirements of
全氟3,4-二甲基己基-3-烯(1)与胺的反应产生的产物直接由亲核作用于(1)引起,但也具有源自攻击性对(1)的异构体的作用,即。全氟3,4-二甲基己-2-烯(2)和全氟-3-亚甲基-4-甲基己烷(3),由反应过程中产生的氟离子促进。所获得的产物关键取决于攻击性胺的空间要求,例如。Et 2 NH给出的产物完全是由对异构体(3)的攻击而产生的。
