Perchloric acid supported on silica gel was found to be an efficient catalyst (2 mol %) for the Hosomi–Sakurai allylation of numerous aldehydes with allyltrimethylsilane in the presence of benzyl alcohol. This method was also effective for the allylation of secondary alcohols under mild experimental conditions.
人们发现,在苄醇存在下,硅胶上负载的高氯酸是将许多醛与烯丙基三甲基硅烷进行Hosomi-Sakurai烯丙基化反应的有效催化剂(2摩尔%)。在温和的实验条件下,该方法对于仲醇的烯丙基化也是有效的。
