A palladium(II)‐functionalized covalent organic framework (Pd@TpBpy COF) constructed from 1,3,5‐triformylphloroglucinol (Tp) and [2,2′‐bipyridine]‐5,5′‐diamine (Bpy) is reported as a recyclable catalyst for conjugate additions in aqueousmedia. Additions of an array of stereoelectronically diverse arylboronic acid nucleophiles to β,β‐disubstituted enones form a variety of ketones containing benzylic
