A new type of non-innocent β-diketiminate ligand having redox active phenol groups ( LH 3 , fully protonated form) has been developed, and the structure, physical properties and reactivity of the supported copper( ii ) complex [Cu II ( L 3− )] − ( L 3− , fully deprotonated tri-anionic form) as well as the one-electron and two-electron oxidised complexes, [Cu II ( L&z.rad; 2− )] and [Cu II ( L − )] + , have been examined in detail. The two-electron oxidised form [Cu II ( L − )] + exhibited hydrogen atom abstraction ability from 1,4-cyclohexadiene (CHD), whereas the one-electron oxidised form [Cu II ( L&z.rad; 2− )] was found to disproportionate into [Cu II ( L 3− )] − and [Cu II ( L − )] + during the course of the reaction with CHD. Structure, physicochemical properties, and reactivity of the copper( ii )-phenoxyl radical complexes of the non-innocent β-diketiminate ligand containing phenol groups are reported.
