Secondary and tertiary alcohols synthesized via allylation of aldehydes and ketones are important compounds in bioactive natural products and industry, including pharmaceuticals. Development of a mechanochemical method using potassium allyltrifluoroborate salt and water, to successfully perform the allylation of aromatic and aliphatic carbonyl compounds is reported for the first time. By controlling
通过醛和酮的烯丙基化合成的仲和叔醇是生物活性天然产物和工业(包括药物)中的重要化合物。首次报道了使用烯丙基三氟硼酸钾盐和水的机械化学方法的开发,以成功进行芳族和脂族羰基化合物的烯丙基化。通过控制研磨参数,该方法可以是选择性的,即对醛非常有效而对酮无效,但是通过使用镧系元素催化剂,与酮的反应实际上可以定量。催化反应也可以在温和的水性搅拌条件下进行。考虑到烯丙基化剂及其副产物,水性介质,能源效率和催化剂的使用,
