The synthesis and characterization of the complexes of Cu(I), Ag(I), Cu(II), and Co(II) ions with 1,2,5-selenadiazolopyridine (psd) is reported. The following complexes have been prepared: [Cu(2)(psd)(3)(CH(3)CN)(2)](2+)2(PF(6)(-)); [(CuCl)(2)(psd)(3)]; [Cu(2)(psd)(6)](2+)2(ClO(4))(-); [Ag(2)(psd)(2)](2+)2(NO(3))(-); [Ag(2)(psd)(2)](2+)2(CF(3)COO)(-); [Cu(psd)(2)(H(2)O)(3)](2+)2(ClO(4))(-)·(psd)(2); [Cu(psd)(4)(H(2)O)](2+)2(ClO(4))(-)·(CHCl(3)); [Cu(psd)(2)(H(2)O)(3)](2+)2(NO(3))(-)·(H(2)O)·(psd)(2), and [Co(psd)(2)(H(2)O)(4)](2+)2(ClO(4))(-)·(psd)(2). The electronic structure of ligand psd, in particular the bond order of Se-N bonds, has been probed by X-ray diffraction, (77)Se NMR, and computational studies. A detailed analysis of the crystal structures of the ligand and the complexes revealed interesting supramolecular assembly. The assembly was further facilitated by the presence of neutral ligands for some complexes (Cu(II) and Co(II)). The molecular structure of the ligand showed that it was present as a dimer in the solid state where the monomers were linked by strong secondary bonding Se···N interactions. The crystal structures of Cu(I) and Ag(I) complexes revealed the dinuclear nature with characteristic metallophilic interactions [M···M] (M = Cu, Ag), while the Cu(II) and Co(II) complexes were mononuclear. The presence of M···M interactions has been further probed by Atoms in Molecules (AIM) calculations. The paramagnetic Cu(II) and Co(II) complexes have been characterized by UV-vis, ESI spectroscopy, and room temperature magnetic measurements.

“…The Cu(0) powder quickly dissolved in an acetonitrile solvent into a colorless solution, similar to the reaction with Cu(I) and Cu(II) salts, suggesting that all copper salts, i. e. Cu(II), Cu(I), and Cu(0), would be converted to the same colorless Cu(I) species in acetonitrile, such as [Cu(CH 3 CN) m (X) (X=OAc, Cl, Br, etc. )], [27] despite their valences. Since Cu(II), Cu(I), and Cu(0) appeared to be equally effective, Cu(OAc) 2 was chosen as a precursor of reactive copper species that is stable and easy‐to‐handle.…”

The C−H oxidation of saturated hydrocarbons to the corresponding alcohols and ketones can be performed efficiently at room temperature with molecular oxygen (1 atm) in the presence of acetaldehyde and catalysts such as Fe, Cu(OH)2, and CuCl2‐18‐crown‐6 complex. Moreover, extremely high turnover numbers (>27,000) have been obtained for the C−H oxidation of saturated hydrocarbons with molecular oxygen (1 atm) using a combination of Cu(OAc)2 and acetonitrile at 70 °C. Related oxidation reactions such as epoxidation, Baeyer‐Villiger reaction, acetoxylation of β‐lactams with molecular oxygen and a suitable aldehyde at room temperature are described.
