  Alkylyttrium Complexes of Amidine–Amidopyridinate Ligands. Intramolecular C(sp³)–H Activation and Reactivity Studies

  摘要：

  The new multidentate amidine-aminopyridine proligand {(NNNCNMe2)-N-Me2-C-Me2-N-Me}H (1) was used in sigma-bond metathesis reactions with the trialkyl precursors Y(CH2-SiMe3)(3)(THF)(2) and Y(CH2C6H4-o-NMe2)(3). These reactions generate the dialkyl complexes {(NNNCNMe2)-N-Me2-C-Me2-N-Me}Y-(CH2SiMe3)(2)(THF) (2a) and {(NNNCNMe2)-N-Me2-C-Me2-N-Me}Y- (CH2C6H4-o-NMe2)(2) (2b), respectively, which were characterized by NMR spectroscopy and microanalysis (for 2b). Complex 2a is unstable at -30 degrees C in toluene and selectively undergoes intramolecular C(sp(3))-H activation to give {(NNNCNMe)-N-Me2-C-Me2-N-Me-CH2}Y(CH2SiMe3)(THF) (2a'), authenticatecl by X-ray crystallography, NMR spectroscopy, and elemental analysis. The reactivity of 2a' toward a number of Lewis and Bronsted acids and bases as well as oxidants and reductants was explored. In the course of these studies, the new complexes {(NNNCNCH2B)-N-Me2-C-Me2-N-Me-C-Me(C6F5)(3)}Y(CH2SiMe3)-(THF) (3), [{(NNNCNCH2)-N-Me2-C-Me2-N-Me-C-Me2}Y(CH2SiMe3)(THF)(x)](+)[BPh4](-) (4), {(NNNCNCH2)-N-Me2-C-Me2-N-Me-C-Me2}Y(iPrNC(PPh2)NiPr) (5), [{(NNNCNMe2)-N-Me2-C-Me2-N-Me)Y{(mu 2BH3)(mu(2)-NH)}](2) (6), and [{(NNNCNCH2)-N-Me2-C-Me2-N-Me-C-Me2(mu-O))Y(CH2SiMe3)](2) (7) were isolated and characterized by NMR spectroscopy and X-ray crystallography and microanalysis (for 6 and 7). Complex 6 was found to be active in the ROP of rac-lactide, affording slightly heterotactic-enriched PLAs.
