AbstractA method for the hydroalkylation of 1,1‐diarylalkenes has been developed using magnesium hydride (MgH2) generated in situ by the solvothermal treatment of magnesium iodide (MgI2) with sodium hydride (NaH) in ethereal solvents. The process is initiated by the hydromagnesiation of 1,1‐diarylalkenes with MgH2 to generate 1,1‐diarylethylmagnesium species, which are immediately alkylated with ethereal solvents to construct a diaryl quaternary carbon center in the hydroalkylation products.
摘要 利用碘化镁(MgI2)与氢化钠(NaH)在乙醚溶剂中的溶解热处理原位生成的氢化镁(MgH2),开发了一种 1,1-二芳基烯烃的氢烷基化方法。该工艺通过 MgH2 对 1,1-二芳基烯烃进行水镁化反应来生成 1,1-二芳基镁,然后立即用乙醚溶剂对其进行烷基化反应,从而在水烷基化产物中形成二芳基季碳中心。
