analysis and intramolecular coordinations N→Ge were evidenced from the two side-chains. In this paper, all known stable and isolated halogermylenes are reviewed. Significant bond lengths of their X-ray structures are reported and compared. Surprisingly, attempts to obtain chlorogermylenes bearing a substituent with a strong electron-withdrawing effect such as 2,4,6-tris(trifluoromethyl)phenyl (Ar′) or
摘要合成了由两个邻侧链供体配体(芳基= 2,6-(CH2NR2)2C6H3,R = Et:1和R = i-Pr:2)稳定的芳基氯亚甲基二甲苯。通过X射线分析表征了1,并且从两个侧链证明了分子内配位N→Ge。本文对所有已知的稳定和分离的卤代亚甲基进行了综述。报告并比较了其X射线结构的重要键长。出人意料的是,尝试获得带有强吸电子效应的取代基的氯二甲苯,例如2,4,6-三(三氟甲基)苯基(Ar')或2,6-双(三氟甲基)苯基(Ar'')。新化合物二芳基氯锗烷Ar'2GeHCl或Ar''2GeHCl。
