Novel germanium containing triflates were prepared from the reactions of trifluoromethanesulfonic acid with tetraphenylgermane (1) and digermanes (Ph3GeGeMe3 (4), Ph3GeGePh3 (5)). The improved procedures for synthesis of known organogermanium compounds (Ph4Ge (1), Ph3GeCl (2), Ph3GeGeMe3 (4), Ph3GeGePh3 (5)) were also presented. The crystal structure of Ph3GeOTf (6) and Ph2Ge(OTf)Ge(OTf)Ph2 (7) was
从三氟甲磺酸与四苯基锗烷(1)和二锗烷(Ph 3 GeGeMe 3(4),Ph 3 GeGePh 3(5))的反应制备了新型的含锗三氟甲磺酸酯。还介绍了改进的合成已知有机锗化合物的方法(Ph 4 Ge(1),Ph 3 GeCl(2),Ph 3 GeGeMe 3(4),Ph 3 GeGePh 3(5))。Ph 3 GeOTf(6)和Ph 2 Ge(OTf)Ge(OTf)Ph 2(7)通过X射线分析进行了研究。在7中,每个锗原子由于与相邻的三氟甲磺酸酯基团的O原子发生分子内相互作用而被五价配位。
