摘要：

Highly reactive cations [Pt(eta4-C4Me4)(solv)x]2+ (solv = acetone or nitromethane) can be obtained from [{Pt(eta4-C4Me4)Cl2}2] by chloride abstraction with AgCFSO3. The solvento complex [Pt(eta4-C4Me4)(Me2CO)x][CF3SO3]2 reacts with cyclopentadienes and with hexamethylbenzene to form the sandwich compounds [Pt(eta4-C4Me4)(dienyl)]CF3SO3 (dienyl = eta5-C5Me5, eta5-C5H4Me or eta5-C5H5) and [Pt(eta4-C4Me4)(eta6-C6Me6)][CF3SO3]2.Me2CO. The new compounds are characterised by H-1, C-13 and Pt-195 NMR spectroscopy and cyclic voltammetry. The structure of the hexamethylbenzene complex, determined by X-ray crystallography, reveals an average Pt-C distance of 2.138 angstrom for the C4Me4 ligand and 2.351 angstrom for the C6Me6 ligand indicating a pronounced structural trans effect.
