摘要

Achiral, diamagnetic Ni (II) complexes 1 and 3 have been synthesized from Ni (II) salts and the Schiff bases, generated from glycine and PBP (7) and PBA (11), respectively, in MeONa/MeOH solutions. The requisite carbonyl-derivatizing agents pyridine-2-carboxylic acid (2-benzoyl-phenyl)-amide 7 (PBP) and pyridine-2-carboxylic acid (2-formyl-phenyl)- amide 11 (PBA) were readily prepared from picolinic acid and o-aminobenzophenone or ...
