The synthesis and structural characterisation, by low temperature X-ray diffraction and solid-state NMR, of the highly reactive monomeric Me3Sn(trop) (1) complex has been studied; 1 rearranges into Me2Sn(trop)2 (2) and Me4Sn by methyl-transfer dismutation. Based on the NMR kinetic data it appears that complex 1 demethylates faster in the solid and liquid than in dilute CDCl3 solution, but with a slower rate than in dilute CD3OD solution.
通过低温X射线衍射和固态核磁共振对高活性单体Me3Sn(trop) (1)复合物的合成和结构表征进行了研究。复合物1通过甲基转移歧化反应重排成Me2Sn(trop)2 (2)和Me4Sn。根据核磁共振动力学数据显示,复合物1在固态和液态中的脱甲基速率比在稀CDCl3溶液中快,但比在稀CD3OD溶液中慢。
