The major effect of replacing Ag(I) with Tl(I) salts, which are indiscriminately used as halide abstractors was investigated. It was found that in the absence of donor ligands such as, OTfs-s or acetonitrile, abstraction of the halide from Pt(II) complex or AgBF4 or AgPF 6 in CH2Cl2 resulted in formation of a dynamic cationic complex. The bonding interactions between the d8 Pt(II) and s2 Tl(I) center was assisted by π-donation from the benzyl ligand to the Tl+ ion.
