摘要:
AbstractThe reactivity of the gold(I) cationic complexes [Au2(StBu)(L2)][BF4] {L = PMe3, PEt3, PtBu3; L2 = dppe [dppe = 1,2‐bis(diphenylphosphanyl)ethane]} was studied. These complexes undergo cleavage of the Au–Au bonds by reaction with phosphanes to give quantitative yields of [Au(StBu)(L)n] and [Au(L)n][BF4] (n = 2 or 3) in the case of monodentate phosphanes, and [Au2(StBu)2(dppe)] and [Au(dppe)2][BF4] in the case of the dppe derivative. These compounds also react with [Au(StBu)(L)] and exchange the neutral moiety bonded to the [Au(L)]+ cation. In both cases some indication of the nature of the intermediates was reached by mass spectrometry (ESI) and NMR spectroscopy. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
