Abstract

Reaction of Na2PdCl4 with Me2NCH2CH2SH·HCl in MeOH affords trimeric PdCl(SCH2CH2NMe2)3. Treatment of M2Cl2(m-Cl)2(PR3)2 (M = Pd or Pt) with Me2NCH2CH2SH.HCl in the presence of NaHCO3 yields MCl(SCH2CH2NMe2)(PR3)n (n = 1 or 2). These complexes were isolated as monomeric species contg. chelating thiolate ligands. In some cases, with more basic phosphines; binuclear complexes (n = 2) contg. bridging thiolate ligands are also formed. All complexes were characterized by elemental anal. and NMR spectroscopy. The structure of PdCl(SCH2CH2NMe2)(PPh3) (2c) was established by x-ray crystallog. on SciFinder(R)
