Abstract

Abstract: Reactions of the complexes cis -[PtCl2 (PPh3 )2 ], [PdCl2 (dppe)] (dppe = Ph2 PCH2 CH2 PPh2 ) and the N, C -cycloaurated gold(III) complexes [AuCl2 (2-benzylpyridyl)] and [AuCl2 (C6 H4 CH2 NMe2 )] with the secondary dithiooxamide EtNHC(S)C(S)NHEt in refluxing methanol with Et3 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}(C6 H4 CH2 NMe2 )], 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. Abstract :
