制备

四苯基锗在1925年被 Gilbert T. Morgan、Harry Dugald 和Keith Drew berichtet报告。它是由四溴化锗和极度过量的格氏试剂苯基溴化镁乙醚反应而成。通过减少格式试剂的量,可以得到一溴、二溴和三溴化物。[3]

之后,四苯基锗可以在甲苯重结晶[4].

性质

四苯基锗是四方晶系的,空间群 P421c (No. 114)。[5]

反应

四苯基锗和卤素卤化物反应,会产生对应的一卤、二卤和三卤化物。

溴和四苯基锗在沸腾的四氯化碳反应,产生三苯基溴化锗:[6]

在其它条件下,则会产生二苯基二溴化锗:[7]

四苯基锗和四氯化锗反应,产生苯基三氯化锗[6]
