The reaction of SPPh2CH2PPh2S with gold(I) or Gold(III) complexes contauning weakly coordinated ligands leads to the formation of the binuclear complexes RAuSPPh2SAuR (R=C6F5), or (ClO4)2, the mononuclear complexes, R3AuSPPh2CH2PPh2S, or ClO4.The last complex reacts with NaH to give R2AuSPPh2CHPPh2S which reacts with Gold(I) or silver(I) derivatives to give binuclear, R2AuSPPh2CHPPh2SAuR, or trinuclear complexes, <(R2AuSPPh2CHPPh2S)2M>ClO4 (M=Au or Ag).Reaction of SPPh2NHPPh2S with RAuTHT, ClAuTHT (THT= tetrahydrothiophen) or 2 gives 2 or R2AuSPPh2NPPh2)S, containing the deprotonated ligand.
