Synthesis, structure, and reactivity of zwitterionic divalent rare-earth metal silanides.
The synthesis and structures of the first zwitterionic divalent rare-earth metal silanides of the formula [Si(SiMe2OMe)3-κ(3)]2M (M-3), where M = Eu, Yb, and Sm, are reported. M-3 compounds feature spirocyclic bicyclooctane structures in which the central rare-earth metal ions are being octahedrally coordinated by six methoxy groups. The reaction of Yb-3 with BPh3 and W(CO)6 respectively genera...

متن کاملSynthesis, structure and reactivity of dinuclear rare earth metal bis(o-aminobenzyl) complexes bearing a 1,4-phenylenediamidinate co-ligand.
A series of phenylenediamidinate rare earth metal complexes 1,4-C6H4[C(NR)2Ln(o-CH2C6H4NMe2)2]2 (R = 2,6-(i)Pr2-C6H3, Ln = Y (2a), Lu (2b), Sc (2c)) were synthesized by deprotonation of 1,4-C6H4[C(NR)(NHR)]2 (1) with two equivalents of n-BuLi followed by reacting with two equivalents of anhydrous LnCl3 and subsequently four equivalents of Li(o-CH2C6H4NMe2), or by protolysis of [Ln(o-CH2C6H4NMe2...
متن کاملRare-earth metal hydroxylamide complexes.
The rare-earth metal hydroxylamide compound Y[N(SiHMe2)2]2[ONBn2][THF] (1) was prepared by the silylamide elimination pathway from the reaction of N,N-dibenzylhydroxylamine, Bn2NOH (Bn = CH2C6H5), with Y[N(SiHMe2)2]3[THF]2 and was characterised by multinuclear NMR spectroscopy and elemental analysis. The compounds [Cp2Y(ONBn2)]2 (2a) [Cp2Sm(ONBn2)]2 (2b) were obtained by the reactions of MCp3 (...
متن کاملRare-earth-metal-hydrocarbyl complexes bearing linked cyclopentadienyl or fluorenyl ligands: synthesis, catalyzed styrene polymerization, and structure-reactivity relationship.
A series of rare-earth-metal-hydrocarbyl complexes bearing N-type functionalized cyclopentadienyl (Cp) and fluorenyl (Flu) ligands were facilely synthesized. Treatment of [Y(CH(2)SiMe(3))(3)(thf)(2)] with equimolar amount of the electron-donating aminophenyl-Cp ligand C(5)Me(4)H-C(6)H(4)-o-NMe(2) afforded the corresponding binuclear monoalkyl complex [({C(5)Me(4)-C(6)H(4)-o-NMe(μ-CH(2))}Y{CH(2)...
