have ligands other than β-dimethylaminoethoxy and could be considered as “organotin analogs of Grignard reagents” have symmetrical dimeric structures, i.e., can be formulated as [Bu2Sn(OMe)(OAc)]2 and [Et2Sn(OMe)Cl]2, respectively. Both types of structures, viz., unsymmetrical adduct (2) and symmetrical dimer (5, 6), have been characterized by X-ray diffraction analysis. (© Wiley-VCH Verlag GmbH & Co
PhSnCl3 与 [Et3Sn(OCH2CH2NMe2)] 的取代基交换反应出乎意料地产生了不对称加合物 [Ph2SnCl2·Ph2Sn(OCH2CH2NMe2)2] (2)。首次明确证明 RSnX3 型化合物能够进行烃取代基再分布反应。类似的锡配合物 [Et2SnCl2·Et2Sn(OMe)2] (5) 和 [Bu2Sn(OAc)2·Bu2Sn(OMe)2] (6),它们具有除 β-二甲氨基乙氧基以外的配体,可被视为“有机锡类似物”格氏试剂”具有对称的二聚体结构,即可以分别表示为 [Bu2Sn(OMe)(OAc)]2 和 [Et2Sn(OMe)Cl]2。两种类型的结构,即不对称加合物 (2) 和对称二聚体 (5, 6),都已通过 X 射线衍射分析进行了表征。(© Wiley-VCH Verlag GmbH & Co.
