An asymmetric synthesis of silicon-stereogenic monohydrosilanes by rhodium-catalyzed dehydrogenative C-H silylation is developed. The process is suitable for the synthesis of various asymmetrically trisubstituted 1-benzosiloles and 1-benzosilolometallocenes in good yields with excellent chemo-, regio-, and stereocontrol. These selected silicon-stereogenic 1-benzosilole compounds exhibit bright blue fluorescence and CPL (circular polarized luminescence) signals, which could be attractive to practitioners of materials science.
开发了一种通过铑催化的脱氢C-H硅氢化反应不对称合成硅立体中心单氢硅烷的方法。该方法适用于以良好的产率、出色的化学、区域和立体控制合成各种不对称三取代的1-苯并硅杂环戊二烯和1-苯并硅杂环戊二烯金属茂。这些选定的硅立体中心1-苯并硅杂环戊二烯化合物表现出亮蓝色荧光和圆偏振发光（CPL）信号，这可能会吸引材料科学领域的从业者。
