Abstract

Abstract : Ion-ion reactions provide access to ion-pairs allowing their role in transmetalation reactions to be explored. Abstract : Gas-phase ion-ion reactions between tris-1, 10-phenantholine metal dications, [(phen)3 M] 2+ (where M = Ni and Mg), and the tetraphenylborate anion yield the ion-pairs {[(phen)3 M] 2+ [BPh4 ] − } + . The ion-pairs undergo transmetalation upon loss of a phen ligand to give the organometallic complexes [(phen)2 M(Ph)] + . DFT calculations, used to determine the energy barriers for the transmetalation reactions and the hydrolysis reactions, are entirely consistent with the experimental results.
