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-aneP_(4)的钼氧配合物,没有立体异构体的产生.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-aneP_(4)is obtained without stereoisomers.
