Macroporous P (GMA-DVB-TRIM) microspheres supported diethylenetriamine palladium complex: An efficient and recyclable catalyst for Heck reactions

Diethylenetriamine-modified macroporous P (GMA-DVB-TRIM) microspheres were used to support palladium (0) nanoparticles applied as a new reusable catalyst for Heck cross-coupling reactions. It shows excellent activity in Heck coupling reactions without an inert atmosphere. The novel macroporous catalyst can be reused at least five times without significant loss of its catalytic activity. (C) 2011 Elsevier B.V. All rights
