Taking shape: The ability of a Lewis acid catalyst to distinguish between aromatic and aliphatic hydrocarbon moieties was accomplished by using cage‐shaped boratecatalysts B(OC6H3Aryl)3CH (see picture) having a πpocket derived from aryl substituents surrounding the boron center. The catalyst predominantly activated aromatic aldehydes over aliphatic ones for reaction.
成形:路易斯酸催化剂区分芳族和脂族烃部分的能力是通过使用笼形硼酸盐催化剂B(OC 6 H 3 Aryl)3 CH(参见图片)实现的,该催化剂的π口袋衍生自周围的芳基取代基硼中心。相比于脂肪族醛,该催化剂主要活化了芳香族醛进行反应。
