Abstract
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-SO3KC6H4) (5) and As(C6H5)2(4-SO3KC6H4) (6) are presented as well.
