摘要：
Two new Mn(II) complexes of bis(2-pyridylmethyl)benzylamine (bpa) were synthesized and characterized by elemental analyses, IR and UV-visible spectroscopies, thermal analyses and ES-MS. These complexes are stable in air with the formula of [(pba)(2)Mn2Cl2(mu-Cl)(2)] (1)and [(pba)(2)Mn-2(H2O)(2)(mu-Ac)(2)] (Ac)(2) (2). The spectroscopic titration results show that the complexes Could react with H2O2 resulting active oxidants, which could cause the intramolecular aromatic hydroxylation. The hydroxylated ligand (pba-OH) was confirmed by ES-MS and HPLC. (C) 2009 Elsevier B.V. All rights reserved.
