Synthesis and characterization of 3-dimethylaminopropyl selenolate complexes of palladium(II) and platinum(II)

Bis(3-dimethylaminopropyl)diselenide was prepd. by the reaction of Na2Se2 with Me2NCH2CH2CH2Cl. 3-Dimethylaminopropylselenolate complexes of Pd and Pt M(SeCH2CH2CH2NMe2)Cl2, M(SeCH2CH2CH2NMe2)2 (M = Pd or Pt), Pd(OAc)(SeCH2CH2CH2NMe2), PtCl(SeCH2CH2CH2NMe2)(PR3)2 (PR3 = PMePh2 or PPr3), Pt(SeCH2CH2CH2NMe2)2(P-P) (P-P = dppm, dppe or 2PPh3) were synthesized by using either the diselenide or its redn. product from the reaction with NaBH4. All complexes were characterized by elemental anal., IR and NMR (1H, 13C, 31P, 77Se, 195Pt) spectroscopy. The stereochem. of these complexes was deduced from the NMR spectroscopic data and the structure of Pd(SeCH2CH2CH2NMe2)Cl2 was established by single crystal x-ray diffraction anal. Each Pd atom in the dimer is surrounded by two m-Se atoms, a N atom and a chloride ligand. on SciFinder(R)
