| 概要 |
Gas phase ion-molecule reactions of CF^+_3 with monosubstituted benzenes have been studied using a thermal-energy ion-beam apparatus. On the basis of product-ion distributions and energetics, the reac...tion mechanism of CF^+_3 with monosubstituted benzenes was classified into the following five cases: (1) PhX (X=H, CH_3): molecular elimination from σ complex, (2) PhX (X=OH, CH_2OH, CH_2CH_2OH, CH(OH)CH_3, OCH_3, NO_2, F, Cl, Br, I): molecular elimination from σ complex or adduct ions formed by the attack on the substituents, (3) PhX (X=CHO, COCH_3, CN, COOCH_3): formation of adduct ions by the attack on the substituent, (4) PhX (X=C_2H_5, OC_2H_5, COC_2H_5, COOC_2H_5): molecular elimination accompanied by Ph-C or C-O bond scission, and (5) PhNH_2: charge transfer.続きを見る
