3-dimethylbutadiene (over Pt) and perfluoro-3,4-dimethylhexa-2,4-diene (over Fe), together with other products. Similar reactions occur with other fluorinated alkenes and the variation between fragmentation and defluorination is rationalised on the basis of the metal used, etc. The fluoride induced reaction between perfluoropropene and perfluorobut-2-ene gives perfluoro-2,3-dimethylpent-2-ene.
在升高的温度下,全氟3,4-二甲基己-3-烯在铁或铂上的通过会导致脱氟和断裂,生成氟化二烯,例如。全氟-2,3-二甲基丁二烯(超过Pt)和全氟-3,4-二甲基六-2,4-二烯(超过Fe),以及其他产品。其他氟化烯烃也会发生类似反应,并且根据所用金属等合理地确定裂解和脱氟之间的差异。全氟丙烯与全氟丁-2-烯之间的氟化物诱导的反应得到全氟-2,3-二甲基戊-2-烯。
