Platinum Stilbazoles: Ring-Walking Coupled with Aryl-Halide Bond Activation

摘要

A metal complex "walking" over electron-rich pi-conjugated systems is believed to be a key process in many chemical transformations involving arene functionalization and activation of strong C-C,C-H,and OX (X = halide) bonds.Despite several experimental and computational studies,ring-walking is often difficult to prove unambiguously,as the vast majority of metal-promoted arene functionalization reactions are bimolecular,require elevated temperatures,and intermediates are not observed.
