Recyclable palladium catalyst cloths for carbon-carbon coupling reactions

Low loading palladium catalyst cloths have been prepared by surface complexation of palladium(II) chloride with plasmachemical imidazole functionalised non-woven polypropylene cloth. For Sonogashira, Mizoroki-Heck, and Suzuki-Miyaura carbon-carbon coupling reactions in conjunction with environmentally friendly solvents, high product yields (54%, 82%, and 99% respectively) and selectivities (99%, 93%, and greater than 99% respectively) have been measured. These palladium catalyst cloths show low levels of metal leaching and can be recycled multiple times.
