Sulfur-containing gold(III) chelates and their use in heterovalent dimer synthesis: Crystal structures of AuIII[CH2P(S)Ph2]2Br, [AuIII[S2P(OH)Ph]2]Cl, and AuIII[CH2P(S)Ph2][S2CN(Et) 2]2

The oxidation of [PPN][Au(CH2P(S)Ph2)2] with Br2 in CH2Cl2 gives the neutral AuIII complex Au[CH2P(S)Ph2]2Br (Au-(MTP)2Br), containing one chelating and one dangling [CH2P(S)Ph2]- (MTP) ligand. The sulfur atom of the chelating MTP ligand is trans to the Br. From 1H NMR studies, the complex in solution is undergoing a dynamic rearrangement on the NMR time scale that exchanges the methylene resonances. The reaction of Au(MTP)2Cl with Au(THT)Cl gives a 2:1 ratio of the heterovalent AuI/AuIII complex Cs-[AuIAuIIIHMTP)2Cl2] and the homovalent AuII-AuII complex Ci-[Au(MTP)Cl]2. The reaction of Au(THT)Cl with NaS2P(OR)Ph, R = Et and H, in THF gives [Au[S2P(OR)Ph]2]Cl. The AuIII complex with R = OH has been characterized crystallographically; in the solid state both the cis and trans isomers are observed. In solution, via 1H NMR spectroscopy, cis and trans interconversion is facile. The reaction of tetraethylthiuram disulfide with [Au(MTP)]2 cleaves the dimer giving Au(MTP)(S2CN(Et)2)2, a single-center, two-electron-oxidation product, rather than a two-center, two-electron-oxidation product. In this complex the MTP is a dangling ligand, carbon bound to the metal atom. One diethyldithiocarbamate ligand is also dangling with the other chelating.
