The intramolecular aryl-phenyl scrambling reaction within palladium-DPPP-aryl complex (DPPP=1,3-bis(diphenylphosphino)propane) ions was analyzed by state-of-the-art tandem MS, including gas-phase ion/molecule reactions. The Mizoroki-Heck cross-coupling reaction was performed in the gas phase, and the intrinsic reactivity of important intermediates could be examined. Moreover, linear free-energy correlations were applied, and a mechanism for the scrambling reaction proceeding via phosphonium cations was assumed.

Organopalladium ArPdL2I (L = tertiary phosphine) complexes (1) can be synthesized in one step from the precursors Pd2(dba)3·C6H6 (2) (dba = t,t-dibenzylideneacetone) and (η3-allyl)PdCp (3) (Cp = η5-cyclopentadienide). Two advantages over previous synthetic methods are that this route requires only stoichiometric amounts of phosphine and that the desired complexes are easily isolated from reaction byproducts. The scope and generality of these reactions are investigated, and the synthesis of a number of new organic- and water-soluble complexes utilizing this methodology is discussed. Improved syntheses of water-soluble ligands P(C6H5)2(4-SO3KC6H 4) (5) and As(C6H5)2(4-SO3KC6H 4) (6) are presented as well.
