  • Lifetimes and UV-visible absorption spectra of benzyl, phenethyl, and cumyl carbocations and corresponding vinyl cations. A laser flash photolysis study
    作者:Frances L Cozens、V M Kanagasabapathy、Robert A McClelland、Steen Steenken
    DOI:10.1139/v99-210
    日期:1999.12.5

    Benzyl (4-MeO, 4-Me, and 4-methoxy-1-naphthylmethyl), phenethyl (4-Me2N, 4-MeO, 3,4-(MeO)2, 4-Me, 3-Me, 4-F, 3-MeO, 2,6-Me2, parent, and 4-methoxy-1-naphthylethyl) and cumyl (4-Me2N, 4-MeO, 4-Me, parent) cations have been studied by laser flash photolysis (LFP) in 2,2,2-trifluoroethanol (TFE) and 1,1,1,3,3,3-hexafluoroisopropanol (HFIP). In most cases styrene or α-methylstyrene precursors were employed for the phenethyl and cumyl ions, the intermediate being obtained by solvent protonation of the excited state. Benzyl cations were generated by photoheterolysis of trimethylammonium and chloride precursors. While a 4-MeO substituent provides sufficient stabilization to permit observation of cations in TFE, cations with less stabilizing substituents usually require the less nucleophilic HFIP. Even in this solvent, the parent benzyl cation is too short-lived (lifetime <20 ns) to be observed. When generated in HFIP, phenethyl cations can be seen to react with unphotolyzed styrene, giving rise to dimer cations that are observed to grow in as the initial phenethyl cation decays. The dimer cations, in common with the oligomer cations seen in cationic styrene polymerization, have a λmax 15-20 nm higher than the monomer and react with both solvent and styrene several orders of magnitude more slowly. This stabilization relative to the phenethyl may reflect an interaction with the aryl group present at the gamma-carbon. Cations 4-MeOC6H4C+(R)-CH3 (R = Me, Et, i-Pr, t-Bu, cyclopropyl, C6H5, 4-MeOC6H4) were generated in TFE via the photoprotonation route. The alkyl series shows that steric effects are important in the decay reaction. The cation with R = cyclopropyl is a factor of 1.5 less reactive than the cation where R = phenyl. Several vinyl cations have also been generated by photoprotonation of phenylacetylenes. ArC+=CH2 has a reactivity very similar to that of its analog ArC+H-CH3, the vinyl cation being slightly (factors of 2-5) shorter-lived. For the various series of cations, including vinyl, substituents in the aryl ring have a consistent effect on the λmax, a shift to higher wavelength relative to hydrogen of 15 nm for 4-Me, 30 nm for 4-MeO, and 50 nm for 4-Me2N.Key words: photogenerated carbocations, carbocation lifetime, styrene, photoprotonation.

    苯甲基(4-MeO,4-Me和4-甲氧基-1-萘基甲基)、苯乙基(4-Me2N,4-MeO,3,4-(MeO)2,4-Me,3-Me,4-F,3-MeO,2,6-Me2,母体和4-甲氧基-1-萘基乙基)和叔丁基(4-Me2N,4-MeO,4-Me,母体)阳离子在2,2,2-三氟乙醇(TFE)和1,1,1,3,3,3-六氟异丙醇(HFIP)中通过激光闪光光解(LFP)进行了研究。在大多数情况下,苯乙烯或α-甲基苯乙烯前体被用于苯乙基和叔丁基离子,中间体通过溶剂质子化激发态而获得。苯甲基阳离子是通过三甲基铵和氯化物前体的光异裂生成的。虽然4-MeO取代基提供了足够的稳定性以在TFE中观察到阳离子,但具有较少稳定取代基的阳离子通常需要较不亲核的HFIP。即使在这种溶剂中,母体苯甲基阳离子也太短寿命(寿命<20 ns)而无法观察到。在HFIP中生成的苯乙基阳离子可以看到与未经光解的苯乙烯反应,导致观察到的二聚体阳离子在初始苯乙基阳离子衰减时增长。与阳离子苯乙烯聚合中观察到的寡聚体阳离子一样,二聚体阳离子的λmax比单体高15-20 nm,并且与溶剂和苯乙烯反应速度慢几个数量级。相对于苯乙基的这种稳定性可能反映了与伽马碳上存在的芳基的相互作用。在TFE中通过光质子化途径生成了4-MeOC6H4C+(R)-CH3(R = Me,Et,i-Pr,t-Bu,环丙基,C6H5,4-MeOC6H4)阳离子。烷基系列表明立体效应在衰减反应中很重要。当R = 环丙基时,其反应性比R = 苯基的阳离子少1.5倍。还通过对苯乙炔的光质子化生成了几种乙烯阳离子。ArC+=CH2的反应性与其类似物ArC+H-CH3非常相似,乙烯阳离子寿命略短(2-5倍因子)。对于包括乙烯在内的各系列阳离子,芳香环中的取代基对λmax有一致的影响,相对于氢的15 nm的4-Me,30 nm的4-MeO和50 nm的4-Me2N的波长偏移。关键词:光产生的碳正离子,碳正离子寿命,苯乙烯,光质子化。

    electrophilicity parameter (E = 9.6) of the 1-phenylethyl cation, 1+, has been determined and combined with the nucleophilicity parameter (N = 0.78, s = 0.95) of styrene (St) to predict diffusion-limited propagation in the cationic polymerization of St by the linear free energy relationship log k = s(N + E). This prediction has been experimentally verified using two different diffusion clock methods, which
