摘　　要：利用简单反应首次合成功能取代的开链二氧四胺配体，此配体含有苯环取代羟甲基侧链，此反应原料易得、产率高．该配体经过元素分析、核磁和红外光谱表征．在（２５．０±０．１）℃，Ｉ＝ ０．１ｍ ｏｌ·ｄｍ － ３ ＮａＮＯ３ 条件下，用ｐＨ法测定了配体的质子化常数、与过渡金属离子铜（Ⅱ）在溶液中的二元配合物稳定常数，并从滴定数据讨论了物种的可能构型．New functionalized open chain dioxotetraamine, which contained hydroxylmethyl groups, was synthesized through simple method with mild reaction condition and higher yield. The new ligand was characterized by element analysis, IR and 1 H NMR. At (25.0±0.1)℃,I=0.1mol·dm -3 NaNO 3, the protonation constants of the new compound and the stability properties of the binary complex of the ligand with transition metal Cu(Ⅱ) were studied by titration method, and rational structures of species in solution were suggested.
