The design and synthesis of a new dipyridyl ligand with appended phenanthryl moieties is described. On addition of increments of silver(I) trifluoromethanesulfonate to a solution of the ligand, the phenanthryl protons shift upfield in the 1H NMR spectrum, suggesting that the phenanthrenes π-stack on coordination of silver(I). In accord with this, the oxidation potential decreased from 1.74 to 1.55
描述了新的带有附加菲基部分的二吡啶基配体的设计和合成。在将三氟甲磺酸银(I)的增量添加到配体的溶液中后,菲质子在1 H NMR光谱中向高场移动,这表明菲在银(I)配位上的π堆积。据此,在银(I)络合时,氧化电位从1.74V降低至1.55V。用钯(II)配位络合物的单晶X射线结构证实了π堆积。
