英文摘要	The N-R-quinolinyl-8-amino ligands HL1-3 (R = 2,6-(Pr2C6H3)-Pr-i (HL1), 2,6-Et2C6H3 (HL2), 2,6-Me2C6H3 (HL3)) have been prepared, which reacted readily with one equiv. of rare earth metal tris(alkyl)s to afford the corresponding bis(alkyl) complexes (LY)-Y-1(CH2SiMe3)(2)(THF) (1) and L1-3Lu(CH2SiMe3)(2)(THF) (2-4) via alkane elimination. Contrastingly, treatment of the in situ generated neodymium tri(alkyl)s with HL1 afforded a mono(alkyl) neodymium complex (5). Complexes 1, 2 and 5 in combination with aluminium alkyls and organoborates established homogenous ternary systems that exhibited versatile catalytic activities and trans-1,4 selectivities for the polymerization of butadiene, depending on the types of aluminium alkyl, organoborate and rare earth metal used. Furthermore, the trans-1,4 selective copolymerization of butadiene and isoprene was achieved by using the ternary system of 1/AlMe3/[Ph3C][B(C6F5)(4)]. Both the kinetics of copolymerization and the thermal behavior of the copolymers were investigated.
