The reaction of the Grignard compound RMgBr, R = 2,4,6-iPr3C6H2, with GeCl2·(dioxane) and SnCl2 furnishes the stannagermene R2GeSnR2 (4) with a short Ge−Sn double bond length of 2.5065(5) Å. Treatment of 4 with dry oxygen at low temperature yields a 3,4-germastannadioxetane with a stretched O−O bond length.
格氏化合物RMgBr的反应,R = 2,4,6- iPr 3 C 6 H 2,GeCl 2 ·(二恶烷)和SnCl 2提供了斯坦纳曼烯R 2 Ge SnR 2(4),具有短的Ge-Sn双键长度为2.5065(5)Å。在低温下用干燥的氧气处理4会生成3,4-germastannadioxetane,具有扩展的O-O键长度。
