| 中文摘要 | reaction of 3-(2-pyridylmethyl)indenyl lithium (1) with lni(2)(thf)(2) (ln = sm, yb) in thf produced the divalent organolanthanides (c5h4nch2c9h6)(2)ln(ii)(thf) (ln = sm (2), yb (3)) in high yield. 1 reacts with lncl(3) (ln = nd, sm, yb) in thf to give bis(3-(2-pyridylmethyl)indenyl) lanthanide chlorides (c5h4nch2c9h6)(2)ln(iii)cl (ln = nd (4), sm (5)) and the unexpected divalent lanthanides 3 (ln = yb). complexes 2-5 show more stable in air than the non-functionalized analogues. x-ray structural analyses of 2-4 were performed. 2 and 3 belong to the high symmetrical space group (cmcm) with the same structures, they are thf-solvated 9-coordinate monomeric in the solid state, while 4 is an unsolvated 9-coordinate monomer with a trans arrangement of both the side-arms and indenyl rings in the solid state. additionally, 2 and 3 show moderate polymerization activities for f-caprolactone (cl). |
