Radical-ligand-derived C-N coupling, Ga(III)-radical vs low-spin Co(III)-radical reactivity
The redox-active ligand 2-(3,5-dimethoxyanilino)-4,6-di-tert-butylphenol, H2LOCH3, results in, as expected, a trisradical complex with a low-spin Co(III) center, [Co-III(L-OCH3 center dot)(3)] (1), whereas the Ga(III) center yields a coordinated new hexadentate monoradical ligand, [(GaL1 center dot)-L-III] (2), presumably due to the ligand-derived redox activity involving C-H activation.
