Z-1,2-Bis(t-butyldimethylsilyl)-1,2-bis(trimethylsilyl)ethylene was prepared, the structure being determined by X-ray crystallography. Remarkably, the compound is fixed to cis configuration and a considerable pyramidarization occurs at olefinic carbons with large twisting of the double bond.
我们制备了 Z-1,2-双(叔丁基二甲基
硅基)-1,2-双(三甲基
硅基)
乙烯,并通过 X 射线晶体学确定了其结构。值得注意的是,该化合物固定为顺式构型,并且在烯烃碳原子上发生了相当程度的
金字塔化,双键发生了很大的扭曲。
