Superacid-derived aluminum catalysts R(2)AlNTf(2) (2 - 5 mol%) are highly efficient and versatile and are suitable promoters for the allylation and pentadienylation of aldehydes, aldol reactions, aldol cross-coupling of ketones, and Michael additions (several products are shown). Furthermore, they can be converted into chemoselective Lewis acids. Tf=trifluoromethanesulfonyl.
超酸衍生的铝催化剂R(2)AlNTf(2)(2-5 mol%)是高效且通用的,是醛的烯丙基化和戊二烯化,醛醇缩合反应,酮的醛醇缩合偶联和迈克尔加成反应的合适促进剂(显示了几个产品)。此外,它们可以转化成化学选择性的路易斯酸。Tf =三氟甲磺酰基。
