英文摘要	Acid-base reaction of Sc(CH2C6H4NMe2-o)(3) with 1 equiv. of pyrrolyl-substituted cyclopentadienyl ligand C4H2Me2NSiMe2C5Me4H in toluene gave the half-sandwich scandium bis(aminobenzyl) complex (C4H2Me2NSiMe2C5Me4)Sc(CH2C6H4NMe2-o)(2) (2). Amine elimination between Sc[N(SiHMe2)(2)](3)(THF) and one equivalent of C4H2Me2NSiMe2C5Me4H afforded the scandium bis(silylamide) complex (C4Me2H2NSiMe2C5Me4)Sc[(NSiHMe2)(2)SiMe2](THF) (3). Both scandium complexes 2 and 3 were characterized by elemental analysis, NMR spectroscopy, and single-crystal X-ray diffraction. 2 and 3 could serve as highly active precursors for styrene polymerization to give syndio-tactic polystyrene (rrrrrr > 99%).
