英文摘要: A new beta-diketimine bearing the pendant pyridyl group, CH3C(2,6-(Pr-i)(2)C6H3NH)CHC(CH3)(NCH2-C5NH4) (L1), was synthesized. The reaction of L1 with one equivalent of Sc(CH2SiMe3)(3)(THF)(2) at room temperature gave a singly deprotonated product (L1-H)Sc(CH2SiMe3)(2) (1). Y(CH2SiMe3)(3)(THF)(2) under the same conditions led to the unexpected dimer [(L1-H-3)Y(THF)](2) ( 2), in which the ligand precursor L1 was triply deprotonated. The reaction of L1 with Y(CH2SiMe3)(3)(THF)(2) at -35 degrees C provided a mixture of singly deprotonated product (L1-H)Y(CH2SiMe3)(2) (3) and doubly deprotonated product (L1-H-2)Y(CH2SiMe3)(THF)(2) (4). The reactions of L1 with Ln[N(SiMe3)(2)](3) gave only singly deprotonated products (L1-H) Ln[N(SiMe3)(2)](2) (5: Ln = Y; 6: Ln = La). The complexes 1, 2 and 4-6 have been characterized by single-crystal X-ray diffraction.
