expected for outer-sphere electron transfer processes. Structure−reactivity relationships are discussed. The excellent correlations between the observed second-order rate constants (log k2) and the previously reported electrophilicity parameters (E) of benzhydrylium ions suggest that several of the compounds investigated in this work can be used as reference nucleophiles for the development of electrophilicity
乙烯酮缩醛与二苯甲基离子的反应动力学已通过光度计跟踪。反应以决定速率的 C-C 键的形成进行,这比外球电子转移过程的预期要快得多。讨论了结构-反应性关系。观察到的二阶速率常数 (log k2) 与先前报道的二苯甲基离子的亲电性参数 (E) 之间的极好相关性表明,这项工作中研究的几种化合物可用作亲核试剂发展的参考亲核试剂。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
