摘要：

The reaction of the lithium salt of the aminodiamide ligand Li-2[(SiMe(3))N{CH2CH2N(SiMe(3))}(2)](Li(2)L) (1) with [TiCl4(THF)(2)] (THF = tetrahydrofuran) forms [TiCl2(L)] (2), from which Ti-IV mono and dialkyl complexes are accessible. The treatment of 2 with Me(2)Mg,LiCH2(SiMe(3)) or LiCH(SiMe(3))(2) results in the formation of [TiMe(2)(L)] (3), [Ti{CH2(SiMe(3))}(2)(L)] (4) or [TiCl{CH(SiMe(3))(2)}(L)] (5) respectively, in which only partial coordination of the amino-nitrogen is observed in solution and the solid state. The X-ray crystal structures of 3 and 5, and an improved synthesis of 1, are described.
