The multigram syntheses of the protio ligands (2-NC(5)H(4))CH(2)N(CH(2)CH(2)NHSiMe(2)R)(2) (R = Me, H(2)N(2)NN' 3; R = (t)Bu, H(2)N(2)NN() 4) are described via reactions of the previously reported (2-NC(5)H(4))CH(2)N(CH(2)CH(2)NH(2))(2) (1). A new synthesis of 1 is reported starting from 2-aminomethylpyridine and N-tosylaziridine, proceeding via (2-NC(5)H(4))CH(2)N(CH(2)CH(2)NHTs)(2) (2). Reaction
蛋白质配体(2-NC(5)H(4))CH(2)N(CH(2)CH(2)NHSiMe(2)R)(2)的克复合合成(R = Me,H(2 )N(2)NN'3; R =(t)Bu,H(2)N(2)NN()4)通过先前报道的(2-NC(5)H(4))CH的反应进行描述(2)N(CH(2)CH(2)NH(2))(2)(1)。据报道新的1的合成从2-氨基甲基吡啶和N-tosylaziridine,开始通过(2-NC(5)H(4))CH(2)N(CH(2)CH(2)NHTs)(2)进行(2)。H(2)N(2)NN'或H(2)N(2)NN *与(n)BuLi的反应给出了二锂衍生物Li(2)N(2)NN'和Li(2)的良好产率N(2)NN *。H(2)N(2)NN'或H(2)N(2)NN *与[MCl(2)(CH(2)SiMe(3))(2)(Et(2)O)( 2)]给出了顺式二氯化物络合物[MCl(2)(L)](L
