Abstract

The reaction of tris(phenylthiomethyl)phosphine with equimolecular amounts of [AuPPh₃]⁺[BF₄]^- affords the complex (tris(phenylthiomethyl)phosphine)(triphenylphosphine)-gold(I) tetrafluoroborate 1 in good yield. The X-ray diffraction analysis of this product shows an unusual conformation with the three CH₂SPh arms of the phosphine folded back towards the metal atom shielding the P-Au-P' unit. The reaction of the same substrate with Bis(tetrahydrothiophene)gold(I) perchlorate in a 1:1 molar ratio leads to the displacement of both weakly coordinated tht ligands, and a dimeric product [AuP(CH₂Sph)₃]₂(ClO₄)₂ 2 is obtained.
