摘要：

A Pd-IV complex that represents a viable catalytic intermediate in Pd-catalyzed C-H bond halogenation reactions has been isolated and structurally characterized. It contains the first examples of both a Pd-IV NHC bond and a Pd-IV alkoxide bond and serves as a precatalyst for C-H bond halogenation. As such, this represents a new class of tunable supporting ligand systems in Pd-IV catalysis.
