Involvement of intramolecular hydride transfer in the formation of alkanes from palladium alkyls

Article abstract of DOI:10.1021/om9703651

Intramolecular hydride transfer in a dimer between Pd atoms and reductive elimination of H and a benzyl moiety to give PhCH₂CH₂C₆F₅ (3) is the main decomposition pathway for the hydrido species generated from the η³-benzylpalladium derivative [Pd₂(μ-Br)₂(η³-CHPhCH₂C ₆F₅)₂] (1). The commonly accepted decomposition of the palladium hydride to give Pd(0) and HX, followed by acid attack on 1 to produce the alkane, is ruled out in this case.
