用双膦处理三（三烯）铂，然后质子化，得到一系列阳离子配合物[Pt（C7 H11）（L2）]+（L2=全烷基双膦），其中三烯基配体通过σ-烷基和β-C-H的agostic相互作用与铂结合，后者的键强度变化，并用n.m.r.和X射线结构分析。
Treatment of tris(norbornene)platinum with diphosphines and subsequent protonation affords a series of cationic complexes [Pt(C7H11)(L2)]+(L2= peralkyldiphosphine) in which the norbornyl ligand binds to platinum viaσ-alkyl and β-C–H agostic interactions; the strength of the latter bond varies and has been characterised by n.m.r. and X-ray structure analysis.
