  The one-pot halomethylation of 5-substituted salicylaldehydes as convenient precursors for the preparation of heteroditopic ligands for the binding of metal salts

  摘要：

  The one-pot bromo- and chloro-methylation of various 5-substituted salicylaldehydes with paraformaldehyde and hydrobromic or hydrochloric acid has been achieved. This approach establishes a convenient and flexible method to attach functional arms to salicylaidehydes for further applications in organic and coordination chemistry. Examples are described using 3-bromomethyl-5-t-butylsalicylaldehyde in the synthesis of piperazine-containing heteroditopic ligands as receptors for metal salts. (c) 2006 Elsevier Ltd.

  [Cu(L-2H)], are selective for Cl- over SO4(2-) in both solvent extraction and bulk liquid membrane transport experiments and were found to bind Cl- in two steps via the formation of a 1:1:1 [Cu(L-H)Cl] assembly, followed by a 1:1:2 [Cu(L)Cl2] assembly as the pH of the aqueous phase is lowered. The anion transport selectivity was evaluated for a number of other mono-charged anions and interestingly

  能够提取金属盐的酰胺官能化的Salen配体已经合成并表征。NiSO4 [Ni（L）（SO4）]配合物的单晶X射线结构测定证实离子载体为两性离子形式，Ni（II）结合在去质子化的salen部分和SO4（2-）中与质子化侧链N'-氨基哌嗪基团相关的离子。用碱处理[Ni（L）（SO4）]会从酰胺基侧基中去除质子，从而导致SO4（2-）离子损失并形成[Ni（L-2H）型仅金属配合物]，其已通过单晶X射线衍射表征。适用于溶剂萃取研究的具有三种溶解度的配体显示出适合从工业浸出溶液中回收CuSO4或CuCl2的加载和汽提pH曲线。仅铜络合物[Cu（L-2H）]在溶剂萃取和体液膜转运实验中对SO4（2-）的Cl-具有选择性，并发现通过形成二价键可分两个步骤与Cl-结合。 1：1：1的[Cu（LH）Cl]组合物，然后是1：1：2的[Cu（L）Cl2]组合物，因为水相的pH降低了。评估了许多其他单电荷阴离子的
