Pd@CN-COF: a pool for palladium(0)-catalyzed reactions

Abstract

A new cyano-substituted olefin-linked COF was synthesized and utilized as a support for palladium nanoparticles. The resulting Pd@CN-COF was demonstrated as a versatile heterogeneous catalyst in crosscoupling reactions, cyanation, and allylic substitution with the productivity exceeding the commercial homogeneous precatalyst [Pd(PPh3)4]. The catalytic activity of Pd@CN-COF was further evaluated in synthetically valuable transformations towards industrially, agrochemically, and pharmacologically relevant products.
