α-Substituted Benzylic Complexes of Palladium(II) as Precursors of Palladium Hydrides Martín Ruiz, Blanca Pérez Ortega, Ignacio Albéniz Jiménez, Ana Carmen Chemistry Organometallic Chemistry Palladium Benzyl complexes Hydrides Transmetalation The adoption of a pseudoallylic (η3) form makes palladium benzylic derivatives a class of stabilized palladium alkyls that can undergo β-H elimination reactions in a more controlled way. α- (Pentafluorophenylmethyl)benzyl palladium complexes have been studied and they decompose by β-H elimination to give palladium hydrides that, depending on the auxil- iary ligands can: a) transmetalate to another palladium atom and, by reductive elimina- tion, give hydrogenated products; this process is favored for a combination of bridging ligands (i.e halogens) and low coordinating ligands. b) Be used as a hydride source and get trapped by a diene to give palladium allylic derivatives. The presence of carbon mon- oxide does not induce a β-H elimination reactions and only CO insertion into the Pd- benzyl bond to give acyl derivatives is observed.
