Disilylketenes undergo selective mono-desilylation upon treatment of t-BuOK in the presence of HMPA. The resulting silylethynolates are convertible to other disilylketenes in good yields. The intermediary silylethynolate was analyzed by NMR and IR spectroscopy.
在 HMPA 的存在下,二硅烷基烯烃经 t-BuOK 处理后会发生选择性单脱硅反应。生成的水杨硫酸盐可以很好地转化为其他二硅烷基烯烃。通过核磁共振和红外光谱分析了中间体水飞蓟醇。
