The reactions of CH3+, CH2F+, CHF2+, and CF3+ with ethene, fluoro-, 1,1-difluoro-, trifluoro-, and tetrafluoro-ethene and with propene, but-1-ene, but-2-ene, and 2-methylpropene have been studied in the gas phase. As well as simple charge exchange, addition reactions were observed in which the initial adduct broke down to yield neutral fragments and ions of either general formula (CnX2n+1)+ or (CnX2n–1)+
CH 3 +,CH 2 F +,CHF 2 +和CF 3 +与乙烯,氟代,1,1-二氟,三氟和四氟乙烯以及丙烯,丁-1-烯的反应,在气相中已经研究了丁-2-烯和2-甲基丙烯。除简单的电荷交换外,还观察到加成反应,其中最初的加合物分解生成中性碎片和离子,通式为(C n X 2 n +1)+或(C n X 2 n –1)+,其中X = H和/或F。初始瞬态加合物离子的断裂通常与氢原子和/或氟原子迁移有关。
