Electrophilic bis-fluorophosphonium dications: Lewis acid catalysts from diphosphines

Stepwise oxidation of 1,8-bis(diphenylphosphino)naphthalene and a series of (oligo)methylene-linked diphosphines with XeF2 followed by fluoride abstraction yields a family of compounds featuring phosphine, phosphonium and phosphorane moieties in close proximity. The bisphosphonium ions [(C10H6)(Ph2PF)2]2+ (5) and [CH2(Ph2PF)2]2+ (9a) exhibit remarkable Lewis acidity arising from the proximity of the phosphonium centers. The effectiveness of bisphosphonium dications (5, 9a-e) is examined in a series of Lewis acid catalysed transformations.

Carbonyl Difluoride: a Versatile Fluorinating Reagent
Gupta, O. D.,Shreeve, Jean'ne M.
, p. 416 - 417 (2007/10/02)
Carbonyl difluoride is a readily accessible reagent for introducing fluorine into molecules by oxidative addition to the central atom or by displacement of hydrogen from P-H, N-H, or C-H bonds.
