protonation for 4-nitrobenzyl halides in aqueous and methanolic dimethyl sulphoxide have been determined. In addition, measurements have been made on some benzylidene and bis-(4-nitrophenyl)methyl halides in aqueous dimethyl sulphoxide. The effects of introducing a second halogen atom or a 4-nitrophenyl group upon both kinetic and thermodynamic acidities are discussed in terms of carbanion structure and solvent
已经确定了4-硝基苄基卤化物在含水和甲醇二甲基亚砜中的质子提取和碳负离子质子化的速率。另外,已经在二甲基亚砜水溶液中对一些亚苄基和双-(4-硝基苯基)甲基卤化物进行了测量。根据碳负离子结构和溶剂效应,讨论了引入第二个卤原子或4-硝基苯基对动力学和热力学酸性的影响。
