  A New Method for the Synthesis of Nonsymmetric Dinucleating Ligands by Aminomethylation of Phenols and Salicylaldehydes

  摘要：

  Monoaminomethylated phenols 5-7 and symmetrically diaminomethylated phenols 8 and 9 were prepared in a one-step procedure-from p-cresol, formaldehyde, and a variety of secondary amines by making use of the aromatic Mannich reaction. Nonsymmetric diaminomethylated phenols 10 and 11 were prepared by a sequential aromatic Mannich reaction using p-cresol, formaldehyde, and two different secondary amines. Alternatively, nonsymmetric diaminomethylated phenols 20-24 were prepared by aminomethylation of 5-methylsalicylaldehyde followed by Ca) condensation with a primary amine and subsequent reduction or (b) reductive amination with a secondary amine. Monoami-nomethylated and (non)symmetric diaminomethylated phenols are excellent ligands for the synthesis of mono- and dinuclear transition metal complexes as is illustrated by the isolation of mononuclear iron(III) complex 25 and nonsymmetric dinuclear copper(II) complex 26.

  A new series of acyclic mono and binuclear copper (II) complexes of the general formula [Cu(L1-5)](ClO4)(H2O)(2) (1-5) and [Cu-2(L1-5)(H2O)(2)](ClO4)(2) (6-10), L1-5 refers to [N-(salicylaldimine)N'-[(2-formyl-4-methyl-6-(4-methylpiperazine-1-yl)methyl)phenol] diamines, where the diamines are L-1 = 1,2-diamino ethane, L-2 = 1,3-diamino propane, 1.3 = 1,2-diamino benzene, L-4 = 2-aminobenzylamine and L-5 = 1,8-diamino naphthalene) have been synthesized and characterized. From the single crystal X-ray diffraction method, the mononuclear complex [Cu(L-1)](ClO4)(H2O)(2) (1), in which the copper atom exhibits a distorted square planar geometry, coordinates with two phenolic oxygen atoms and two ethylenediamine nitrogen atoms. The coordination bond angles have values between 83.7(2)degrees [N1-Cu1-N2] and 94.08(19)degrees [O2-Cu1-N2]. Electrochemical studies were performed using cyclic voltammetry, in which the appearance of one quasi-reversible peak within the potential range -0.91 to -1.21 V (E-pc) for mononuclear and two quasi-reversible peaks within the potential ranges -0.70 to -0.88 V (E-pc(1)) and -0.96 to -1.15 V (E-pc(2)) for binuclear complexes were observed respectively. The CT-DNA binding ability of the complexes was investigated using absorption and fluorescence spectroscopic studies, viscosity measurements and circular dichroic techniques. In the absorption spectra, the binding constant (K-b) values for all the complexes were found to be of the order of 0.4 x 10(4)-5.5 x 10(4) and from fluorescence spectra the apparent binding constant (K-app) values were of the order of 1.7 x 10(6)-6.6 x 10(6). From the above K-b and K-app values, the binding propensity of the complexes to CT-DNA is revealed to be through the intercalative mode. The complexes cleave supercoiled pBR322 DNA in the presence of mercaptoethanol as a reducing agent and with a mechanistic pathway involving the formation of singlet oxygen as a reactive oxygen species. Overall, the more aromatic containing binuclear Cu(II) complex (10) exhibits better DNA binding and cleavage activity than the substituted aliphatic complexes. (C) 2013 Elsevier Ltd.
