英文摘要	Amine elimination between rare-earth metal tris(amide) complexes Ln [N(SiHMe2)(2)](3) (THF)(x) and 1 equiv. of pyrrolyl-substituted cyclopentadienyl ligand C4H4NSiMe2C5Me4H was investigated. Reaction of C4H4NSiMe2C5Me4H and Ln [N(SiHMe2)(2)](3) (THF)(x) with small metals afforded the half-sandwich rareearth metal bis(silylamide) complexes (C4H4NSiMe2C5Me4) Ln [N(SiHMe2)(2)](2) (Ln = Sc (1), Y (2)), while the same reaction using La [N(SiHMe2)(2)] (3) (THF)(2) isolated lanthanum mono-silylamide complex [C5Me4SiMe2N(SiHMe2)(2)] La [N(SiHMe2)(2)](C4H4N) (3). These complexes were characterized by elemental analysis and NMR spectroscopy. 1 and 3 were structurally authenticated by single crystal X-ray diffraction. The ternary catalyst systems of 1 or 2/AliBu(3)/[Ph3C][B(C6F5) (4)] showed activity towards styrene polymerization to give pure syndio-tactic polystyrenes (rrrr > 99%).
