On and off: The concerted [2+1] cycloaddition reaction of phosphine–silylene complexes with ethylene affords the corresponding pentacoordinate siliranes. The conversion is strongly related to the ethylene pressure, and the reaction is reversible at room temperature. The structure of one silirane was determined by X‐ray diffraction analysis.
开和关:膦-亚甲硅烷基络合物与乙烯的协同[2 + 1]环加成反应提供相应的五配位甲硅烷基。该转化率与乙烯压力密切相关,并且该反应在室温下是可逆的。一种Xilaneane的结构是通过X射线衍射分析确定的。
