[LO(3)}M](+)[X](-) (M = Zn, 8; Mg, 9; Ca, 10; Sr, 11; Ba, 12) and [RO(3)}M](+)[X](-) (M = Zn, 13; Mg, 14; Ca, 15; Sr, 16; Ba, 17) were synthesized in high yields (70-90%) by reaction of 3 or 4 with the neutral precursors M[N(SiMe(3))(2)](2)(THF)(x) (M = Zn, Mg, x = 0; M = Ca, Sr, Ba, x = 2). All compounds were fully characterized by spectroscopic methods, and the solid-sate structures of compounds 1, 3, 7, 8, 13
已经设计了用于合成大碱土 (Ae) 金属 (Ca、Sr、Ba) 及其较小的 Zn 和 Mg 类似物的明确、无溶剂阳离子的有效协议。2,4-二叔丁基-6-(吗啉甲基)苯酚(LO(1)}H), 2-[双(2-甲氧基乙基)氨基]甲基}-4,6-二-叔丁基苯酚 (LO(2)}H), 2-[(1,4,7,10-tetraoxa-13-azacyclopentadecan-13-yl)methyl]-4,6-di-tert-butylphenol (LO (3)}H) 和 2-[(1,4,7,10-tetraoxa-13-azacyclo-pentadecan-13-yl)methyl]-1,1,1,3,3,3-hexafluoropropan-2 -ol (RO(3)}H) 与 [H(OEt(2))(2)](+)[H(2)NB(C(6)F(5))(3)}( 2)](-) 很容易得到双酸性前配体
