英文摘要	Four mono(boratabenzene) rare-earth metal dialkyl complexes, [(3,5-Me-2-C5H3BR)Ln(CH2SiMe3)(2)(THF)] (1: R = NEt2, Ln = Sc; 2: R = NEt2, Ln = Lu; 3: R = Ph, Ln = Sc; 4: R = Ph, Ln = Lu), were synthesized efficiently via a one-pot strategy with Li[3,5-Me-2-C5H3BR] (R = NEt2, Ph), LnCl(3)(THF)(x) (Ln = Sc, x = 3; Ln = Lu, x = 0), and LiCH2SiMe3. The solid-state structures of 1 and 2 were determined by single-crystal X-ray diffraction. Variable-temperature NMR studies indicated that the energy barrier for the rotation of amino-boratabenzene in 1 (Delta G double dagger approximate to 71 kJ mol(-1)) is higher than that of phenylboratabenzene in 3(Delta G double dagger approximate to 59 kJ mol(-1)). These mono(boratabenzene) rare-earth metal dialkyl complexes' catalytic behaviors for styrene polymerization were investigated, and found that mono(boratabenzene) scandium dialkyl complexes show high catalytic activities for syndiotactic polymerization upon activation with cocatalysts.
