- 中文摘要: The interactions of the ligand N, N′-bis-(β-carbamoylethyl)-ethylenediamine (BCEN) with copper (II) in aqueous solution have been investigated by potentiometric and spectrophotometric techniques. The two protonation constants of the ligand at 25° in 0.2 M NaNO3 are 10… and 10…. The quantitative equilibrium studies if the stepwise reactions which precede the formation of CuBCEN2+ and the Cu=O to Cu-N bond rearrangements at the two amide sites are described in detail. Electronic spectra of the copper (II) chelates formed are measured and discussed.
