用循环伏安法和理论计算系统地研究了动力学稳定的双腈类化合物BbtE=EBbt [E = P，Sb，Bi; Bbt = 2，6-双[双（三甲基硅基）甲基]-4-[三（三甲基硅基）甲基]苯基]的氧化还原行为.结果表明，它们在还原区表现出可逆的单电子氧化还原对。通过还原相应的中性双腈类化合物（BbtP=PBbt和BbtSb=SbBbt），成功地合成了Bbt取代的双膦和二苯乙烯的阴离子自由基物种。通过ESR、UV-vis和拉曼光谱对其结构进行了表征，并通过X射线晶体学分析对其结构进行了表征。
The redox behavior of kinetically stabilized dipnictenes, BbtE=EBbt [E = P, Sb, Bi; Bbt = 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl], was systematically disclosed using cyclic voltammetry and theoretical calculations. It was found that they showed reversible one-electron redox couples in the reduction region. The anion radical species of the Bbt-substituted diphosphene and distibene were successfully synthesized by the reduction of the corresponding neutral dipnictenes (BbtP=PBbt and BbtSb=SbBbt). Their structures were reasonably characterized by ESR, UV-vis, and Raman spectroscopy, and the distibene anion radical was structurally characterized by X-ray crystallographic analysis.
