A palladium(II)-functionalized covalent organic framework (Pd@TpBpy COF) built from 1,3,5-triformylphloroglucinol (Tp) and [2,2'-bipyridine]-5,5'-diamine (Bpy) is reported as a recyclable catalyst for conjugate additions in aqueous media. Additions of an array of stereoelectronically diverse arylboronic acid nucleophiles to β,β-disubstituted enones form a variety of ketones containing benzylic all-carbon quaternary centers in up to 92 % isolated yield. Research on the recyclability of Pd@TpBpy COF demonstrate this catalyst remains active through at least 7 cycles and shows superior stability to related MOF catalysts with bipyridine linker units.
