中文摘要: |
大环四齿膦配体通常以Ni(Ⅱ)、Pd(Ⅱ)、Pt(Ⅱ)或者Cu(Ⅰ)为模板合成,并且在合成大环四齿膦配体时很难避免异构体的产生,而第六副族过渡金属只报道过用于大环三齿膦配体的合成.以Mo(Ⅳ)为模板,在其上构筑了一种平面大环四齿膦配体.首先设计并合成了一种具有两个含磷小环的开链四齿膦配体.经过随后的配位和烷基化,得到含有大环四齿膦配体17-aneP4的钼氧配合物,没有立体异构体的产生. |
英文摘要: |
Macrocyclic tetradentate phosphine ligands are usually synthesized using Ni(Ⅱ), Pd(Ⅱ), Pt(Ⅱ) or Cu(Ⅰ) as templates, and it is difficult to avoid the generation of isomers during the synthesis of macrocyclic tetradentate phosphine ligands. The group-ⅥB transition metals have only been reported for the synthesis of macrocyclic tridentate phosphine ligands. Herein, a planar macrocyclic tetradentate phosphine ligand is constructed on a Mo(Ⅳ) template. Firstly, an open-chain tetradentate phosphine ligand with two P-containing small rings is designed and synthesized. Then, after coordination and alkylation, a molybdenum-oxo complex featuring a macrocyclic tetradentate phosphine ligand 17-aneP4 is obtained without stereoisomers. |
