Treatment of the gold(I) halide complexes LAuCl (where L=PMe₃, PEt₃, PPh₃, PPh₂Py) and PP(AuCl)₂ [where PP=bis(diphenylphosphino)methane; 1,1′-bis(diphenylphosphino)ferrocene] with 4-amino-2-pyrimidine-thiol (2-SPym-4-NH₂) (one or two equivalents as required) in the presence of sodium methoxide provides the corresponding (phosphine)gold(I) thiolate complexes LAu(2-SPym-4-NH₂) and PP[Au(2-SPym-4-NH₂)]₂, respectively. A polyaurated product [(Ph₃PAu)₂(2-SPym-4-NH₂)]BF₄ is obtained on treating the thiol with the oxonium complex [(Ph₃PAu)₃O]BF₄. The compounds LAu(2-SPym-4-NH₂) (L=PPh₃, PPh₂Py, PEt₃) and [(dppm)Au₂(2-SPym-4-NH₂)₂] have been investigated crystallographically.
