摘要: The ditriflate salt of the DMAP-stabilized trimethylphosphane dication is formed from reaction chlorotrimethylphosphonium triflate with DMAP (4-dimethylaminopyridine) in presence trimethylsilyltriflate and also DMAP-dimethylphosphenium methyltriflate. coordinative nature DMAP–phosphorus bond demonstrated by a ligand exchange for PMe3 to give hexamethyldiphosphonium dication.
