Novel fluorinated mono-enes and di-enes have been synthesised via telomerisation reactions using (CF3)2CFI with CF2CH2 and also with CF2CFH. Cyclo-additions with diazomethane occur readily to give Δ1 or Δ2 pyrazolines, depending on the system, and nucleophilic attack occurs with methanol and with fluoride ion. In the latter case, stable carbanions have been observed. A novel free-radical route to
新颖的氟化单-烯和二-烯已经通过调聚反应使用已经合成(CF 3)2 CFI与CF 2 CH 2并且还与CF 2 CFH。环加法用重氮甲烷容易想到,得到Δ 1或Δ 2个吡唑啉,取决于系统,和亲核攻击用甲醇和用氟离子发生。在后一种情况下,观察到稳定的碳负离子。一种新型自由基路线七元环,从环加成二甲基-和二乙基-醚至二烯[(CF产生3)2 CCHCF 2 - ] 2(3), 已经被开发出来。
