The reaction of [(Ph3As)AuCl] with Ag2O in the presence of NBF4 in tet
rahydrofuran affords three products, identified as [(Ph3As)(4)Au]BF4 (
40.3%), [(Ph3As)(2)Au]BF4 (16.4%) and {[(Ph3As)Au](3)O}BF4 (17.3%). Th
e properties of the main product agree well with recent literature dat
a. The other two compounds are new and have been identified by their a
nalytical, spectroscopic, and crystallographic data. The structures ar
e isomorphous with those of the analogous Ph3P complexes. Variations i
n the stabilities are discussed in terms of kinetic and thermodynamic
effects.
