The magnesium complexes L2Mg i Pr (L2= 4-tert-butyl-6-(triphenylsilyl)-2-[bis ((3- (dimethylamino) propyl) amino) methyl] phenoxyl) and L3Mg i Pr (L3= 4-tert-butyl-6- (triphenylsilyl)-2-[benzyl ((3-(dimethylamino) propyl) amino) methyl] phenoxyl) supported by potentially tetradentate and tridentate triphenylsilyl-substituted phenoxyamine ligands have been prepared and fully characterized. The complexes were shown to be competent ...
