The first stable 9-germaanthracene and 9-germaphenanthrene were successfully synthesized by taking advantage of kinetic stabilization utilizing effective steric protection groups, Tbt and Bbt groups (Tbt = 2,4,6-tris[bis(trimeth-ylsilyl)methyl]phenyl, Bbt = 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl). The similarities and differences of the structures and properties between
利用有效的空间保护基团,Tbt和Bbt基团(Tbt = 2,4,6-三[双(三(三甲基-甲硅烷基)甲基]苯基], Bbt = 2,6-双[双(三(甲基硅烷基)甲基] -4- [三(三甲基硅烷基)甲基]苯基。讨论了芳香芳香族化合物的两种异构体在结构和性质上的异同。
