Abstract

The oxidation of the earlier synthesized [4,6-di-tert-butyl-N-(2,6-diisopropylphenyl)-o-amidophenolato]methylgallium(iii) (1a) and [4,6-di-tert-butyl-N-(2,6-diisopropylphenyl)-o-amidophenolato]iodogallium(iii) (1b) by different reagents, such as mercury(ii) salts, molecular iodine, and tetramethylthiuram disulfide, was studied. The oxidation of the starting diamagnetic compounds gives pentacoordinated gallium(iii) bis-o-iminosemiquinolates 4–7 as the major products, which are generated as a result of the further disproportionation of intermediate monoradical tetracoordinated metal complexes.
