Control of C-H activation by proximal metal-ligand interaction and its application to selective transformation reaction of saturated hydrocarbons

制备了带有桥联聚亚甲基单元的“野餐篮”状过渡金属络合物。观察到区域选择性的分子内CH-金属(d轨道)相互作用。通过调节亚甲基间隔物的长度和配体的结构可以实现对C-H活化位置的远程控制。

Transition metal complexes with “picnic basket” shaped structures bearing bridged polymethylene unit were prepared. Regioselective intramolecular CH-metal (d orbital) interaction was observed. Remote controlling of the position of C-H activation can be performed by tuning of methylene spacer length and the structure of ligands.
