Didocosyl selenide stabilized recyclable Pd(0) nanoparticles and coordinated palladium(II) as efficient catalysts for Suzuki-Miyaura coupling.

First selenium ligand stabilized Pd(0) nanoparticles (∼3-5 nm) catalyze Suzuki-Miyaura C-C coupling in short time and are recyclable (up to 94% yield after 5 reuses). The air stable compound [PdCl(2)(L1)(2)] shows high catalytic efficiency for this coupling as its 3 × 10(-5) mol% is sufficient for activated ArBr.
