Abstract

The immobilisation of an oxime-based palladacycle on polyvinylpyridine (PVP) resin affords a reusable, air, moisture and thermally stable palladium precatalyst which exerts high activity in Suzuki-Miyaura reactions both in batch as well as continuous-flow processes. Evidence is presented which shows that, besides serving as an anchor for the precatalyst, PVP also acts as a scavenger for Pd particles present in solution.
