Metal-Organic Proximity in a Synthetic Pocket

摘要

Proximity between a noninteractive organic substrate and a transition metal (trans-MCl_2(PEt_3)_2; M = Pd or Pt) is achieved by their co-encapsulation within a synthetic cage, as revealed by X-ray crystallographic analysis and NOESY experiments. Through co-encapsulation with a Pd(Ⅱ) complex, a terminal alkyne was activated within the cage to give a σ-alkynylpalladium complex.
