Abstract

p-Phenylenediphosphine 1,4-C₆H₄(PH₂)₂, synthesized according to a published procedure, has been fully characterized by its analytical and spectroscopic data. This diprimary phosphine was reacted with 2 equiv of (LAu)₃O⁺BF₄⁻ (L = t-Bu₃P or Ph₃P) to yield products of the type [1,4-(LAu)₃P−C₆H₄−P(AuL)₃]²⁺(BF₄⁻)2 with two trigold moieties in the dications. The reaction of 2 equiv of an equimolar mixture of (Ph₃PAu)₃O⁺BF₄⁻ and Ph₃PAu⁺BF₄⁻ with 1,4-C₆H₄(PH₂)2 leads to the product [1,4-(Ph₃PAu)₄P−C₆H₄−P(AuPPh₃)₄]⁴⁺(BF₄⁻)₄ in quantitative yield, which features two tetranuclear units in trans positions. The compounds were obtained as polycrystalline solids, which were readily identified by means of a detailed NMR and mass spectrometric analysis.
