Abstract

A PdIV 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 PdIV NHC bond and a PdIV 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 PdIV catalysis.
