electron‐withdrawing groups. By applying this novel catalytic system, a general protocol for the Rh‐catalysed hydroformylation‐hydrogenation of unsymmetrical internal alkynes, functionalized with a carboxylic acid, was found to furnish aliphatic aldehydes in high regio‐ and chemoselectivities. Control experiments confirm the enzyme‐like supramolecular catalyst mode of action.
基于通过引入吸电子基团提高膦配体的π-受体能力的策略,设计了具有酰基胍基功能的新的超分子配体。通过应用这种新颖的催化系统,发现了用羧酸官能化的不对称内部炔烃进行Rh催化加氢甲酰化-加氢的通用方案,可提供具有高区域选择性和化学选择性的脂族醛。对照实验证实了类似酶的超分子催化剂的作用方式。
