摘要：
Metalation of dipyrromethene (dipyrrin) (la-c) with Ni(OAc)(2) provides Ni-dipyrrole complexes (NiL2) (2a-c) in 37-47% yields. The complexes were characterized by mass spectrometry and UV-Vis absorption, H-1 NMR spectroscopy and single crystal X-ray. In CH2Cl2, each compound undergoes two reversible one-electron reductions and one irreversible oxidation wave. In DMF, complexes 2a-c also undergoes two reversible one-electron reductions but with three irreversible oxidation waves were observed. The effect of substituents and solvent on redox potentials is discussed. (C) 2015 Elsevier Ltd. All rights reserved.
