✦ Synopsis

Abstract

The copper‐catalyzed Huisgen reaction between azides and alkynes was utilized to covalently attach derivatives of 4‐(dimethylamino)pyridine (DMAP) to a polystyrene resin (PS) support. The catalytic potential of these constructs as determined in acylation and aza‐Morita–Baylis–Hillman reactions far exceeds that of commercially available DMAP‐PS resins and is fully competitive with DMAP in homogeneous solution.
