Abstract

The reaction of [(Ph₃As)AuCl] with Ag₂O in the presence of NaBF₄ in tetrahydrofuran affords three products, identified as [(Ph₃As)₄Au]BF₄ (40.3%), [(Ph₃As)₂Au]BF₄ (16.4%) and {[(Ph₃As)Au]₃O}BF₄ (17.3%). The properties of the main product agree well with recent literature data. The other two compounds are new and have been identified by their analytical, spectroscopic, and crystallographic data. The structures are isomorphous with those of the analogous Ph₃P complexes. Variations in the stabilities are discussed in terms of kinetic and thermodynamic effects.
