coordinated sulfur is observed in these derivatives, and the dynamic process has been studied for the monomeric complexes [(σ-κS-(Rthio)alkyl)Pd(acac)] (13b, 14b, 18b, 19b). ΔG⧧Tc values show that the S-inversion is easier for the Ph-substituted than for the n-Bu-substituted complexes. The decomposition of the σ-yl-κS palladacycles occurs through Pd-migration and, when Pd and S are placed three bonds apart

But-3-enyl butyl sulphide forms chelate complexes of general formula [PdX2,L](X = Cl or Br) and [PtX2,L](X = Cl, Br, or l); and n-butyl pent-4-enyl sulphide forms chelate complexes of formula [PtX2,L](X = Cl, Br, or l), in which co-ordination to the metal occurs through both the olefinic double bond and the sulphur atom. These complexes react with unidentate ligands such as p-toluidine and triphenylphosphine
