α-Substituted Benzylic Complexes of Palladium(II) as Precursors of Palladium Hydrides

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...
