  Intramolecular Alkylation of α-Diimine Ligands Giving Amido—Imino and Diamido Scandium and Yttrium Complexes as Catalysts for Intramolecular Hydroamination/Cyclization

  摘要：

  Treatment of alkyl complexes M(CH2SiM3)(3)-(THF)(2) (1a M=Sc; 1b M =Y) with alpha-dumine ligands, N, N'-bis(2,6-dimethylphenyl)-1,4-diaza-1,3-butadiene (2a) and N, N'-bis(2,6-dusopropylphenyl)-1,4-diaza-1,3-butadiene (2h), afforded the corresponding amido-imino complexes M(CH2-SiMe3)(2)(2,6-R2Ph-DAB-CH2SiMe3)(THF) (3a M = Sc, R = M = Sc, R = Me, 3b. M = Sc, R = 'Pr, 4a M = Y, R = Me, 4b. M = Y, R = 'Pr) by selective monoalkylatron of one of two C=N bonds of the ligands followed by intramolecular 11 migration, while in the reactions with a less bulky alpha-dimine ligand, N,N'-bis(4-methylphenyl)-1,4-diaza-1,3-butadiene (2c), complex la gave an diamido complex ScCH2SiMe3(4- MePh-DAB-(CH2SiMe3)(2))-(THF)(2) (5c) as a product of the double alkylation Upon heating a hexane solution of 3b, intramolecular activation of a C-H bond of an isopropyl group of the ligand proceeded to give a scandium monoalkyl complex ScH2SiMe3(CH2C2H4-6-'PrPh-2,6'Pr2Ph-DAB-DH2SiMe3)(THF) (6h). Among them, amido-imino complexes of yttrium became catalysts for intramolecular hydroamination/cylization of 2,2-dimethyl-4-pentenylamine at at room temperature
