three-step synthesis of C3-symmetric trisilasumanene and trigermasumanene, heteroanalogues of the π-bowl sumanene, was achieved using a threefold rhodium-catalyzed cyclodehydrogenation of Si/Ge–H and C–H bonds as the key step. Trigermasumanene was proven to adopt a planar geometry by single crystal X-ray diffraction for the first time. The optical properties were also investigated by UV–vis and fluorescence
通过三步
铑催化的Si / Ge-H和C-H键的环脱氢反应,实现了C 3对称的三
硅氢苏曼烯和Trigermasumanene的三步合成,它们是π碗苏南烯的杂类似物。Trigermasumanene首次通过单晶X射线衍射被证明具有平面几何形状。还通过紫外可见光谱和荧光光谱研究了光学性质。
