1,4-双(二苯基膦)丁烷 | 1,4-di(diphenylphosphino)-butane | 7688-25-7 | C28H28P2 | 426.478 |
A series of electrophilic bis-fluorophosphonium dications dervied from diphosphines with naphthalene- and (oligo)methylene-linkers is presented. The resulting Lewis acidity is demonstrated to depend on the spatial proximity between the P moieties as evidenced in several Lewis acid catalyzed transformations.
