Rare earth metal bis(alkyl) complexes bearing amino phosphine ligands: Synthesis and catalytic activity toward ethylene polymerization
Reactions
of neutral amino phosphine compounds HL1-3 with rare earth metal tris(alkyl)s,
Ln(CH2SiMe3)(3)(THF)(2), afforded a new family of organolanthanide complexes,
the molecular structures of which are strongly dependent on the ligand
framework. Alkane elimination reactions between 2-(CH3NH)-C6H4P(Ph)(2) (HL1)
and Lu(CH2SiMe3)(3)(THF)(2) at room temperature for 3 h ge...

Rare earth metal alkyl complexes bearing N,O,P multidentate ligands: Synthesis, characterization and catalysis on the ring-opening polymerization of L-lactide
Alkane
elimination reactions of rare earth metal tris(alkyl)s,
Ln(CH2SiMe3)3(THF)2 (Ln = Y, Lu) with the multidentate ligands HL1-4, afforded
a series of new rare earth metal complexes. Yttrium,
complex I supported by flexible amino-intino phenoxide ligand HL1 was isolated
as homoleptic product. In the reaction of rigid phosphino-imino phenoxide
ligand HL ...

Alternating Copolymerization of Cyclohexene Oxide and Carbon Dioxide Catalyzed by Noncyclopentadienyl Rare-Earth Metal Bis(alkyl) Complexes
The
syntheses of several dialkyl complexes based on rare-earth metal were
described. Three beta-diimine compounds with varying N-aryl substituents (HL1 =
(2-CH3O(C6H4))N=C(CH3)CH=C(CH3)NH(2-CH3O(C6H4)), HL2 = (2,4,6-(CH3)(3)
(C6H2))N=C(CH3)CH=C(CH3)NH(2,4,6-(CH3)(3)(C6H2)), HL3 = PhN=C(CH3)CH(CH3) NHPh)
were treated with Ln(CH2SiMe3)(3)(THF)(2) to give dialkyl complexes L(1)Ln
(CH2SiMe...

Synthesis and Characterization of Heteroscorpionate Rare-Earth Metal Dialkyl Complexes and Catalysis on MMA Polymerization
A
series of rare-earth metal alkyl complexes supported by a heteroscorpionate
ligand were prepared and structurally characterized. X-ray diffraction analysis
revealed that the heteroscorpionate ligand is face-capping on the rare-earth
metal in k(3) mode, making the configuration of the afforded chalky! metal
complexes similar to that of half-metallocenes. These complexes are capable of
polymeriz...
