项目摘要
The main purposes of this project are the development of novel ligands bearing steric protection group and their application toward the synthesis and isolation of novel dynamic complexes bearing unique chemical bonds between heteroatoms. We have succeeded in the synthesis of the extremely bulky bidentate ligand, {Bbt(Me)PCH_2}_2 (1), and its platinum complex, [PtCl_2(1)](2). In this year, we attempted to synthesize the corresponding zero valent platinum complex, [Pt(1)](3), which should be a good precursor for the unprecedented platinum complex bearing a Pt=S double bond, [PtS(1)]. Although reduction of 2 using sodium shot or lithium naphthalenide was attempted, no evidence for the generation of 3 was observed. On the other hand, we succeeded in the synthesis of a new lithium β-diketiminate bearing Tbt and mesityl (Mes) groups, [Li{TbtNC(Me)CHC(Me)NMes}] (4), which is the first heteroatomrdonor-free monomeric lithium β-diketiminate. Lithium β-diket-iminate 4 reacted with MCl_4(thf)_2 (M = Ti, Zr, Hf) to give the corresponding group 4 metal complexes [M{TbtNC(Me)CHC(Me)NMes}(thf)n] (5a : M = Ti, n = 0, 5b : M = Zr, n = 1, 5c : M = Hf, n = 1), respectively. The reduction of 5a-c with KC_8 in the presence of tmeda and LiCl was found to afford unexpected imido complexes [M(NTbt)-{MesNC(Me)CHC(Me)}(μ-Cl)_2Li(tmeda)] (6a : M = Ti, 6b : M = Zr, 6c : M = Hf) in good yields. The treatment of hafnium complex 6c in benzene with KC_8 gave imido complex [HfCl(NTbt)- {MesNC(Me)CHC(Me)}(thf] (7c) in 82% yield in the absence of additives. These imido complexes 6a-c and 7c are most likely formed via the corresponding divalent group 4 metal complexes.
该项目的主要目的是开发带有空间保护基团的新型配体及其在杂原子之间带有独特化学键的新型动态配合物的合成和分离中的应用我们已经成功合成了极其庞大的二齿配体{Bbt。 (Me)PCH_2}_2 (1) 及其铂配合物[PtCl_2(1)](2) 今年,我们尝试合成相应的零价铂配合物, [Pt(1)](3),它应该是前所未有的带有 Pt=S 双键的铂络合物的良好前体,[PtS(1)] 尽管尝试使用钠丸或萘化锂还原 2,但没有成功。另一方面,我们成功合成了带有 Tbt 和基团 (Mes) 的新 β-二酮亚胺锂。 [Li{TbtNC(Me)CHC(Me)NMes}] (4),这是第一个与MCl_4(thf)_2 (M = Ti, Zr, Hf) 得到相应的第 4 族金属配合物 [M{TbtNC(Me)CHC(Me)NMes}(thf)n] (5a:M = Ti,n = 0,5b:M = Zr,n = 1,5c:M = Hf,n = 1),在 tmeda 和 LiCl 存在下,用 KC_8 还原 5a-c。发现提供意想不到的亚氨基配合物 [M(NTbt)-{MesNC(Me)CHC(Me)}(μ-Cl)_2Li(tmeda)] (6a : M = Ti, 6b : M = Zr, 6c : M = Hf) 在苯中用 KC_8 处理铪络合物 6c 得到亚氨基络合物 [HfCl(NTbt)- {MesNC(Me)CHC(Me)}(thf]。 (7c) 在没有添加剂的情况下,产率为 82% 这些酰亚胺络合物 6a-c 和 7c 最有可能是通过相应的二价基团形成的。 4 金属配合物。
