The transition metals used were Ni,Cu,Fe(II),Fe(III),Mn, Cr and Zn. The ligands used were pyridine,CN^-,acethylacetone,dimethylglyoxime, EDTA and polyamine, which were En,Dien,Trien and Tetren. Ni and Cu were excellent in conversion but inferior to Co, the result of which was reported previously. The reactivity increased in the following order : Co>Ni>Cu>Fe(II).No reaction occured in the other metals. Polyamine was superior to other ligands in selectivity. In the case of CN^-,azoxybenzene was obtained at 60?70°C. Phenylhydroxylamine was produced in the case of the Cu complex of pyridine or Trien.}, pages = {69--77}, title = {いくつかの遷移金属錯体と水素化ホウ素ナトリウムによるニトロベンゼンの選択還元}, volume = {5}, year = {1973} }
