摘要

We report M(IV) M = Ti, Zr, Hf, Ce, and Th, complexes of a selenium bis(phenolate) ligand, 2,2'-selenobis(4,6-di-tert-butylphenol), ((H2OSeO)-O-Ar), 1. Reaction of Ti(NEt2)(4) with two equivalents of 1 affords Ti((OSeO)-O-Ar)(2), 2. Salt metathesis of ZrCl4 and HfCl4 with two equivalents of (Na2OSeO)-O-Ar produces Zr((OSeO)-O-Ar)(2)(THF), 3, and Hf((OSeO)-O-Ar)(2)(THF), 4, respectively. Protonolysis of ThCl[N(SiMe3)(2)](3) with two equivalents of 1 yields Th((OSeO)-O-Ar)(2)(THF)(2), 5. Salt metathesis of Ce(OTf)(3) and two equivalents of (Na2OSeO)-O-Ar produces [Na(THF)(3)][Ce((OSeO)-O-Ar)(2)], which was oxidized in situ using 0.5 equivalents of I-2 to yield the diamagnetic Ce(IV) product, Ce(ArOSeO)(2)(THF)(2), 6. Addition of 2,2'-bipyridyl to 6 forms Ce((OSeO)-O-Ar)(2)(bipy), 6a. Each diamagnetic complex was characterized using H-1, C-13, and Se-77 NMR and IR spectroscopy and the structures of 2-6a were established with X-ray crystallography. Electrochemical measurements using cyclic voltammetry on complexes 2, 5, and 6 are also reported.

ZrCl4和HfCl4的盐复分解与两个当量的(Na 2 OSeO)-O-Ar分别生成Zr((OSeO)-O-Ar)(2)(THF)3和Hf((OSeO)-O-Ar)(2)(THF)4, ThCl [N(SiMe3)(2)](3)的2当量为1的质子分解反应生成Th((OSeO)-O-Ar)(2)(THF)(2),5。Ce(OTf)的盐复分解(3)和两当量的(Na2OSeO)-O-Ar生成[Na(THF)(3)] [Ce((OSeO)-O-Ar)(2)],使用0.5当量的I将其原位氧化-2得到抗磁性Ce(IV)产物Ce(ArOSeO)(2)(THF)(2),6。将2,2'-联吡啶基加成6种形式的Ce((OSeO)-O-Ar)( 2)(bipy),6a。使用H-1,C-13和Se-77 NMR和IR光谱对每个反磁性配合物进行表征,并通过X射线晶体学确定2-6a的结构。还报道了使用循环伏安法对配合物2、5和6进行电化学测量。
