Palladium ethylthioglycolate modified silica—a new heterogeneous catalyst for Suzuki and Heck cross-coupling reactions

A novel heterogeneous silica supported palladium ethylthioglycolate catalyst which is active and recyclable for Suzuki and Heck reactions is reported.

A new silica supported sulfur containing ethylthioglycolate material that readily binds Pd from solutions of palladium acetate is reported. This affords an active and recyclable solid phase catalyst for Suzuki and Heck reactions with no evidence of Pd leaching. Figure optionsDownload as PowerPoint slide
