ortho-metalation of benzylic tert-butyl thioethers efficiently promote C–C coupling reactions and were studied mechanistically in the Suzuki reaction. The catalytic reaction was monitored by 19F NMR and GC–MS and the decomposition of the S-palladacycle was studied under stoichiometric conditions, showing that these palladacycles serve as a reservoir of zerovalent palladium species. The formation of these species
