AbstractThe synthesis, structures and catalytic activities of three organolanthanide complexes supported by the H(3)tpa ligand (H(3)tpa = tris(pyrrolyl-alpha-methyl) amine) are described. Treatment of H(3)tpa with one equivalent of Ln[N(SiMe3)(2)](3) (Ln = Sc, Sm, Dy) in THF gives, after recrystallization from toluene/THF solution, Sc(tpa)(THF)(2) (1), Sm(tpa)(THF)(3) (2) and Dy(tpa)(THF)(3) (3) in good yields. The structures of complexes 1-3 were determined by single-crystal X-ray diffraction and elemental analysis. Complexes 2 and 3 exhibited good catalytic activity for the polymerization of epsilon-caprolactone.
