In the pocket: The supramolecular interactions between a Rh phosphine catalyst equipped with an anion‐binding pocket and alkenes that contain anionic functionalities (see picture) provide an excellent design concept to achieve remote control of the regioselectivity in hydroformylation reactions. The 4‐pentenoate and 3‐butenylphosphonate, which fit tightly between the Rh center and the pocket, were
囊中之物:配备有阴离子结合囊的Rh膦催化剂与包含阴离子官能团的烯烃之间的超分子相互作用(参见图片)提供了出色的设计理念,可远程控制加氢甲酰化反应中的区域选择性。紧密位于Rh中心和口袋之间的4-戊烯酸酯和3-丁烯基膦酸酯以前所未有的选择性加氢甲酰化。
