Abstract

Reactions of the organoplatinum complex [Pt(cod)(neoSi)Cl] (neoSi = (trimethylsilylmethyl)) with the Ag(I) salts of oxo or fluoride containing anions A(-) = NO3-, ClO4-, OTf- (trifluoromethanesulfonate) and SbF6- lead to the desired abstraction of the chlorido ligand and precipitation of AgCl. However, further reaction of the resulting Pt complexes [Pt(cod)(neoSi) (solvent)](+) with diverse N-heterocyclic ligands L such as pyridines, caffeine, and guanine did not yield the targeted complexes [Pt(cod)(neoSi)(L)](A) in most of the cases, but to extensive decomposition yielding [Pt(cod)(Me) (solvent)](+), thus transforming the neoSi into a methyl ligand. A detailed study on the reaction with SbF6- combining DFT calculations with NMR and MS revealed that Pt catalysed decomposition of SbF6- and fluorination of the neoSi silicon atom leading to FSiMe3. When reacting the parent complex with Ag(BPh4), the arylated derivative [Pt(cod)(neoSi)(Ph)] was obtained and characterised by multinuclear NMR, MS and single crystal XRD.
