Pd−Smopex-111: A New Catalyst for Heck and Suzuki Cross-Coupling Reactions

Smopex-111, a commercially available metal-scavenging styryl thiol-grafted polyolefin fiber was treated with palladium acetate giving a reagent with a palladium loading of 4.4−4.7 (wt %). The Pd−Smopex-111 thus generated was found to be a highly active catalyst for Heck and Suzuki coupling reactions and was found to be reusable with negligible leaching of palladium.
