Catalytic performance of methacrylate‐based poly‐4‐(dialkylamino)‐pyridines: activity prediction via NMR shifts

Abstract

By alkylation, the catalytic activity of 1‐(4‐pyridyl)piperazine‐bearing polymethacrylates is improved. The catalytic efficiency of polymer‐attached 4‐(dimethylamino)pyridine (4‐DMAP) analogues correlates remarkably well with the NMR chemical shifts of their β‐pyridyl protons.
