| 中文摘要 | the synthesis and catalytic activity of lanthanide monoamido complexes supported by a beta-diketiminate ligand are described. donor solvents, such as dme, can cleave the chloro bridges of the dinuclear beta-diketiminate ytterbium dichloride {[(dipph)(2)nacnac]ybcl(mu-cl)(3)yb[(dipph)(2)nacnac](thf)} (1) [(dipph)(2)nacnac = n,n-diisopropylphenyl-2,4-pentanediimine anion] to produce the monomeric complex [(dipph)(2)nacnac]ybcl2(dme) (2) in high isolated yield. complex 2 is a useful precursor for the synthesis of beta-diketiminate-ytterbium monoamido derivatives. reaction of complex 2 with 1 equiv of linpr2i in thf at room temperature, after crystallization in thf/toluene mixed solvent, gave the anionic beta-diketiminate-ytterbium amido complex [(dipph)(2)nacnac]yb(npr2i)(mu-cl)(2)li(thf)(2) (3), while similar reaction of complex 2 with linph2 produced the neutral complex [(dipph)(2)nacnac]yb(nph2)cl(thf) (4). recrystallization of complex 3 from toluene solution at elevated temperature led to the neutral beta-diketiminate-lanthanide amido complex [{(dipph)(2)nacnac}yb(npr2i)(mu-cl)](2) (5). the reaction medium has a significant effect on the outcome of the reaction. |
