As simple as it gets! Potassium tert‐butoxide alone catalyzes the direct dehydrogenative SiO coupling of several synthetically important silanes with 1°, 2°, and even 3° alcohols without the need for stoichiometric hydrochloric acid scavengers. The stereoretentive mechanism is probed with a silicon‐stereogenic silane.
就这么简单!钾叔丁醇单独催化直接脱氢的Si 的几个合成重要硅烷与1 O联接°,2°,甚至3°醇,而不需要化学计量的盐酸清除剂。立体固位机理是通过硅立体烷硅烷来探测的。
