This work describes a base-mediated borylsilylation of benzylic ammonium salts to synthesize geminal silylboronates bearing benzylic proton under mild reaction conditions. Deaminative silylation of aryl ammonium salts was also achieved in the presence of LiOtBu. This strategy which is featured with high efficiency, mild reaction conditions, and good functional group tolerance provides efficient routes
这项工作描述了碱介导的苄基铵盐的硼基甲硅烷基化,以在温和的反应条件下合成带有苄基质子的孪晶甲硅烷基硼酸酯。在 LiO t Bu存在下也实现了芳基铵盐的脱氨基甲硅烷基化。该策略具有高效、反应条件温和、官能团耐受性好的特点,为胺类的后期官能化提供了有效途径。
