with 2-methoxyphenyl isocyanide one Ge−Ge double bond is cleaved to give the 4(1H)-trigermatimine ring system with an endocyclic Ge−Ge double bond and the known tetrakis(2,4,6-triisopropylphenyl)digermene (10). All new compounds were characterized by X-ray crystallography. Redetermination of the structure of 10 revealed two independent molecules with GeGe bond lengths of 2.2894(6) and 2.2635(14) Å, respectively
在Et 3 P存在下用硒处理六(2,4,6-三异丙基苯基)tetragermabuta-1,3-diene(2)可以提供具有内环Ge-Ge双键的selenatetragermacyclopentene衍生物。2与少量水反应生成类似于THF的草酸酯-germamacyclopentane。2与Et 3 PTe的反应通过裂解所有Ge-Ge键进行,以产生1,2,4,5-tetratellura-3,6-digermacyclocyclic衍生物以及少量的“双层”化合物R 4 Ge 4 Te 6,R = 2,4,6- i Pr 3 C 6 H 2,以及telluradigermirane。在2与2-甲氧基苯基异氰化物的反应中,一个Ge-Ge双键被裂解,得到带有内环Ge-Ge双键和已知的四(2,4,6-三异丙基苯基)的4(1 H)-trigermatimine环系统digermene(10)。所有新
