In comparison to the chemistry of monomeric Pd(II) species containing ?1- or ?3-allyl ligands relatively little is known about Ni(I) and Pd(I) dimers that contain bridging allyl moieties. Even less is known about Ni(I) and Pd(I) dimers that are bridged by cyclopentadienyl (Cp) or indenyl ligands. Here, we describe the synthesis of a variety of dimers which contain a combination of bridging allyl, Cp or indenyl ligands and are all supported by either PEt3 or NHC ligands. The solid state geometries, electronic structures and reactivity of these new compounds will be compared and the activity of these complexes for cross-coupling reactions is described. In particular, the nature of the bridging ligand can alter the HOMO of the Pd(I) dimers, which we believe influences the reactivity of these complexes.
