Synthesis and investigation of phosphine ligands containing cationic guanidino functions in aqueous Heck reactions

Article abstract of DOI:10.1016/0040-4020(94)01101-5

Phosphines 2 and 3 supplemented with strongly basic and hydrophilic guanidium functions were prepared for the first time. In combination with palladium acetate these ligands form active catalysts that promote an aqueous Heck reaction.
