C–F bond cleavage by transient phosphorus(III)-based dications [RP(C(PPh3)2)]2+ (4a2+, R = Ph; 4b2+, R = 4-F-Ph) is reported. These dications were generated by reaction of the corresponding monocationic precursors with excess Na[BAr4Cl]. Evidence for the existence of transient dicationic species was...
