Reduction of a Chelating Bis(NHC) Palladium(II) Complex to [{μ-bis(NHC)}₂Pd₂H]⁺: A Terminal Hydride in a Binuclear Palladium(I) Species Formed under Catalytically Relevant Conditions

Half‐way house: The first palladium(I) N‐heterocyclic carbene complex has been isolated in high yield by the base‐assisted reduction of a palladium(II) precursor. The location of the unique terminal hydride (see picture; PdI cyan, H white, N blue) was established by neutron crystal structure determi...

Zusammenfassung:	Half‐way house: The first palladium(I) N‐heterocyclic carbene complex has been isolated in high yield by the base‐assisted reduction of a palladium(II) precursor. The location of the unique terminal hydride (see picture; PdI cyan, H white, N blue) was established by neutron crystal structure determination, and the solution fluxional behavior of the complex was explored.
