Fast I/Sm and Br/Sm exchanges take place when various aromatic or heterocyclic iodides and bromides are treated with nBu2SmCl⋅4 LiCl and nBu3Sm⋅5 LiCl, respectively. The resulting organosamarium reagents were efficiently quenched with aldehydes, ketones, and imines. Also, they undergo acylations when treated with N,N‐dimethylamides leading to ketones. The rate of the Br/Sm exchange for a typical aryl
当分别用n Bu 2 SmCl·4 LiCl和n Bu 3 Sm·5 LiCl处理各种芳族或杂环碘化物和溴化物时,会发生快速的I / Sm和Br / Sm交换。将所得有机sa试剂有效地用醛,酮和亚胺淬灭。同样,当用N,N-二甲基酰胺处理时,它们会发生酰化反应,生成酮。确定了典型的芳基溴的Br / Sm交换速率,发现其比Br / Mg交换快8.5×10 5,这表明金属交换速率与碳的离子特性有关。金属键和对金属的电负性。
