We report the design, synthesis, characterization, and operation of a [2]rotaxane in which a palladium-complexed macrocycle can be translocated between 4-dimethylaminopyridine and pyridine monodentate ligand sites via reversible protonation, the metal remaining coordinated to the macrocycle throughout. The substitution pattern of the ligands and the kinetic stability of the Pd-N bond means that changing
我们报告了 [2] 轮烷的设计、合成、表征和操作,其中
钯络合的大环可以通过可逆质子化在 4-二甲
氨基吡啶和
吡啶单齿
配体位点之间易位,
金属始终与大环协调。
配体的取代模式和 Pd-N 键的动力学稳定性意味着在没有额外输入(热和/或配位溶剂/阴离子)。因此,在环境条件下,可以选择、操作、分离和表征 [2] 轮烷的四组质子化和中性、稳定和亚稳定共构体中的任何一个。
