Six ferrous chloride complexes ((Ar-BIANX)FeCl2: Ar = 2,6-diisopropylphenyl (Dipp), X = F (1), Cl (2), Me (3); Ar = mesityl (Mes), X = F (4), Cl (5), Me (6)) supported by sterically bulky asymmetric bis(arylimino)acenaphthene (BIAN) ligands were prepared through the treatment of anhydrous FeCl2 with the corresponding ligands in a molar ratio of 1 : 1. The compounds were characterized by X-ray crystallography
六种氯化亚铁络合物((Ar-BIAN X)FeCl 2:Ar = 2,6-二异丙基苯基(Dipp),X = F(1),Cl(2),Me(3); Ar =异丁基(Mes),X = F(4),Cl(5),Me(6))通过无水FeCl 2的处理制备,由空间庞大的不对称双(芳基)))(BIAN)配体支撑与相应配体的摩尔比为1:1。通过X射线晶体学,IR,NMR和电化学方法对化合物进行表征。该系列配合物代表了带有不对称双齿BIAN配体的结构特征铁化合物的罕见实例。测试了该络合物在室温下对醛和酮的催化氢化硅烷化作用,水解后获得了中等至良好收率的醇衍生物。
