Our research group is targeting reactive, charge neutral zwitterions of the late transition elements; we hope to expose reaction chemistry reminiscent al electrophilic or truly cationic late metal centers. Recently we prepared an anionic, bidentate phosphine ligand and studied its ability to support C-H activation chemistry at a divalent platinum center. Hoping to explore new systems relevant to polymerization catalysis and organic transformations we are now targeting related palladium and nickel species. For example, we have prepared a palladium(ll) alkyl complex. {Ph_2B(CH_2PPh_2)_2}Pd(Me)(THF), strategically designed to mimic the highly active, cationic palladium copolymerization catalyst [(dppp)PdMe(OEt_2)][Bar_4]. This presentation will address the following general question: Can charge neutral complexes containing borate counter-anions tethered to but insulated from late metal centers be used for desirable stoichiometric and catalytic transformations. Furthermore, how does the chemistry of these neutral zwitterions compare with that of their more familiar discrete salt or ion-paired counterparts?
