More Information
Summary:Reactions of the complexes cis-[PtCl 2 (PPh 3 ) 2 ], [PdCl 2 (dppe)] (dppe = Ph 2 PCH 2 CH 2 PPh 2 ) and the N,C-cycloaurated gold(III) complexes [AuCl 2 (2-benzylpyridyl)] and [AuCl 2 (C 6 H 4 CH 2 NMe 2 )] with the secondary dithiooxamide EtNHC(S)C(S)NHEt in refluxing methanol with Et 3 N base gave good yields of the respective neutral dithiooxamide complexes containing a doubly deprotonated dithiooxamide ligand. The Pt and Pd complexes, as well as [Au{SC(NEt)C(NEt)S}(C 6 H 4 CH 2 NMe 2 )], were characterized by single-crystal X-ray diffraction. In all complexes the ligand is S,S-bonded to the metal center. The complexes were also characterized by NMR spectroscopy and ESI mass spectrometry.
