tert-butyl groups, while the bis(trimethylsilyl)methyl substituent was not affected. One tert-butyl group was transferred to an alkoxide which in the dimeric formula unit of the product 2 occupies the bridging position between both gallium atoms. The second one afforded a terminally arranged tert-butylperoxo ligand by the insertion of a complete oxygen molecule into the respective Ga-C bond. Another
用氧处理 (Me3C)2Ga-CH(SiMe3)2 (1) 会氧化叔丁基的两个季碳原子,而双(三甲基甲硅烷基)甲基取代基不受影响。一个叔丁基被转移到醇盐,在产物2的二聚式单元中,该醇盐占据两个镓原子之间的桥接位置。第二个通过将完整的氧分子插入相应的 Ga-C 键中,提供了末端排列的叔丁基过氧配体。另一种有机过氧化镓 (5) 是通过 Li(OEt2)[H3GaCH(SiMe3)2](3) 与 HOO-CMe2OMe (4) 的反应获得的。三氢没食子酸酯的两个氢化配体被过氧基团取代,而第三个 Ga-H 键通过插入单个氧原子产生氢氧化物 (Ga-OH)。产物 Li[Ga(OH)(OOCMe2OMe)2R] [5, R=CH(SiMe3)2],
