资源简介：
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 obtained by
trapping the dication 4a2+ with
PMe3. According to theoretical analysis, the low-lying
lowest unoccupied molecular orbitals of these species were responsible
for the observed activation of C–F bonds.
