Bis-2-thienyldiethylaminophosphane (C4H3S)2PNEt2 (1) is introduced as a ligand for late transition metal complexes ([(H3C4S)2PNEt2]nMXmLp), with M = Ni(II), Au(I), Cu(I), Pd(II), Ir(I), X = Cl, Br and L = NCMe, COD, (2-7). Reactions of 1 with the late transition metal salts NiCl2·dme, (Me2S)AuCl, CuCl, PdCl2(PhCN)2, and [Ir(COD)Cl]2 yield the complexes [(H3C4S)2PNEt2}2 · NiCl2] (2), [(H3C4S)2PNEt2 · AuCl] (3) [(H3C4S)2PNEt2·CuCl(CH3CN)]2 (4), [(H3C4S)2PNEt2}2 · PdCl2] (5), [(H3C4S)2PNEt2}2·PdCl2]2 (6), and [(H3C4S)2PNEt2·IrCl(COD)] (7). In addition, the transformation of 1 to the valuable chlorine-substituted starting material (H3C4S)2PCl (8) and the related conversion of 8 to the secondary phosphane (H3C4S)2PH (9) is reported. The complexes 2-7 are stable under inert gas conditions and were characterized by single-crystal X-ray studies, NMR spectroscopy, and elemental analysis.
