Sulfonated N-heterocyclic carbenes for Suzuki coupling in water†
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
