Bis(trimesitylgermylcarbodiimido)germylene (1), isolated as a white precipitate from the reaction of lithium trimesitylgermylcyanamide with dichlorogermylene, is stable at room temperature in the absence of water and oxygen. The germylene structure is preserved in the reaction with 3,5-di-t-butylcatechol, while subsequent addition to 3,5-di-t-butylorthoquinone gave the corresponding spirogermane. Thermal
从三苯三甲基锗基氰氨化锂与二氯亚锗烯的反应中分离出白色沉淀形式的双(三苯甲基锗基碳二亚胺基)亚甲基(1)在室温下在没有水和氧气的情况下是稳定的。所述锗烯结构被保留在反应与3,5-二-吨-butylcatechol,而随后加入到3,5-二-吨-butylorthoquinone得到相应spirogermane。1的热分解在50°C左右发生,从而导致生成双(三甲锗烷基)碳二亚胺和聚碳二亚胺基亚二甲基。水解1得到两种同分异构形式的相应的氰酰胺单酸酯化衍生物(3):均三甲苯基氰胺(3a))和三苯三茂基碳化二亚胺(3b),在溶液中处于平衡状态。异构体3b是第一种从苯溶液中沉淀出来的化合物。通过X射线衍射确定其结构。化合物3在加热时分解以形成双氰胺和双(三甲基锗烷基)碳二亚胺。
