摘要
Two dianionic amine bis(phenolate) ligands are introduced and their reactions with titanium tetra( iso-propoxide) studied; ligand I having a single N-donor group leads exclusively to a homoleptic Lig(2)Ti type complex whereas ligand 3 having an additional N-donor on a side arm leads exclusively to a LigTi(OPri)(2) type complex.
