Abstract
Sulfonated, water-soluble imidazolium and imidazolinium salts were synthesized and the respective Pd-complexes with N,N′-bis(2,6-dialkyl-4-SO3−-phenyl)imidazol-2-ylidene and N,N′-bis(2,6-dialkyl-4-SO3−-phenyl)-4,5-dihydroimidazol-2-ylidene ligands were applied in aqueous Suzuki coupling reactions of aryl chlorides.
