The equilibrium profiles for [1,5]-silatropic shifts in a series of 1,3-/1,1-disilyl substituted indenes were studied by NMR and computational methods based on density functional theory. Both methods indicate higher activation parameters for the [1,5]-shifts than observed in monosilyl substituted indene analogues.
通过核磁共振和基于密度泛函理论的计算方法研究了一系列1,3- / 1,1-二甲硅烷基取代的茚并[1,5] -silatropic位移的平衡曲线。与在单甲硅烷基取代的茚类似物中观察到的相比,两种方法均显示出更高的[1,5]位移活化参数。
