  Synthesis, Structural Characterization, and Reactivity of Mono(amidinate) Rare-Earth-Metal Bis(aminobenzyl) Complexes

  摘要：

  Three kinds of solvated lithium amidinates with different coordination models were obtained via recrystallization of [PhC((NC6H4Pr2)-Pr-i-2,6)(2)]Li(THF) (1a) in different solvents. Treatment of o-Me2NC6H4CH2Li with LLnCl(2)(THF)(n) (2; L = [PhC((NC6H4Pr2)-Pr-i-2,6)(2)](-) (NCNdipp), [o-Me2NC6H4CH2C-((NC6H4Pr2)-Pr-i-2,6)(2)](-) (NCNdipp)) formed in situ from reaction of LnCl(3)(THF)(x) with LLi(THF) gave the rare-earth-metal bis(aminobenzyl) complexes LLn-(CH2C6H4NMe2-o)(2) (L = NCNdipp, Ln = Sc (3a), Y (3b), Lu (3c); L = NCNdipp, Ln = Sc (3d), Lu (3e)) in high yields. Reactions of complexes 3 with CO2, PhNCO, 2,6-diisopropylaniline, and S have been explored. CO2 inserted into each Ln-C bond of complexes 3a-c to form the dual-core complexes [(NCNdipp)Sc(mu-eta(1):eta(1)-O2C CH2C6H4NMe2-o)(2)](2) (4a) and [(NCNdipp)Ln(mu-eta(1):eta(2-)/O2CCH2C6H4NMe2-o)(mu-eta(1):eta(O2CCH2C6H4NMe2)-O-2-o)](2) (Ln = Y (4b), Lu (4c)). The reaction of 3b,c,e with PhNCO produced LLu[OC(CH2C6H4NMe2-o)NPh](2)(thf) (L = NCN&PP, Ln = Y (5b), Lu (5c);.L = NCNdipp, Ln = Lu (Se)). Protonolysis of 3a,b by 2,6-diisopropylaniline formed straightforwardly the mu(2)-imido complexes [(NCNdipp)Ln(mu-(NC6H4Pr2)-Pr-i-2,6)](2) (Ln = Sc (6a), Lu (6c)). Reaction of 3e with S-8 afforded the sulfur insertion products (NCNdipp')(CH2C6H4NMe2-o)(SCH2C6H4NMe2-o)(thf) (7e) and (NCNdipp)Lu(SCH2C6H4NMe2-o)2(thf)(2) (7f) in high yields, respectively, depending on the stoichiometric ratio. All of these complexes were fully characterized by elemental analysis, NMR spectroscopy, and X-ray structural determinations.
