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
Using a non-labile Co (III) metal template and click reaction followed by de-metalation, synthesis of [2], linear [3], and radial [4] catenane has been achieved. Synthesized templated linear [2] catenane has an additional metal binding site for the synthesis of higher-order catenane through post-functionalization.
使用不稳定的 Co (III) 金属模板和点击反应,然后进行脱金属,已经实现了 [2]、线性 [3] 和径向 [4] 索烯的合成。合成的模板线性[2]索烯具有额外的金属结合位点,用于通过后官能化合成高阶索烯。
