Article abstract of DOI:10.1039/DT9850000159

The high preference of phenylazoacetaldoxime, MeC(=NOH)N=NPh (HL), for copper(I) is rationalised in terms of electronic and steric factors.The complex (1) undergoes a one-electron oxidation at ca. 0.8 V vs. saturated calomel electrode to an unstable Cu(II)Cu(I) species.Tertiary phosphines displace HL from (1) affording . (2a) reacts with HCl to form <4> and with HClO4 to give the complex .All complexes having the chelated CuL or Cu(HL) fragment are shown to have a characteristic low-energy metal-to-ligand charge-transfer transition (700-900 nm).
