Abstract

Stable gold(I) cations: Treatment of [AuCl(SMe2)] with AgSbF6 in CH2Cl2 at room temperature in the presence of norbornene leads smoothly to the formation of a complex containing the homoleptic tris(η2-norbornene)gold(I) cation (see figure). The complex shows appreciable stability in the solid state and may be stabilised in solution by the addition of excess norbornene.
