method for the preparation of multidentate ligands comprised of a multi-imine platform derived from 1,1,1-tris(aminomethyl)ethane or tris(aminoethyl)amine connected to bi- and tridentate N-donor chelates has been developed. The feasibility of the method has been demonstrated through the synthesis and characterization of a large set of these ligand types. Complexation to Cu(I) was accomplished for several
已经开发了制备多齿配体的一般方法,该方法包括衍生自与双齿和三齿N-给体螯合物连接的1,1,1-三(氨基甲基)乙烷或三(氨基乙基)胺的多亚胺平台。通过大量这些配体类型的合成和表征,证明了该方法的可行性。在多种情况下都完成了与Cu(I)的络合,生成了三铜和四铜(I)络合物,这些络合物已在溶液中通过NMR光谱和电导率表征,并在固态下通过元素分析,质谱和/或X-射线晶体学。这些复合物可能对建模多铜蛋白活性位点有用。
