Title: | C-F bond activation by transient phosphenium dications | Authors: | Đorđević, Nemanja Tay, Madelyn Qin Yi Muthaiah, Senthilkumar Ganguly, Rakesh Dimić, Dušan Vidović, Dragoslav |
Issue Date: | 4-May-2015 | Journal: | Inorganic chemistry | Abstract: | C-F bond cleavage by transient phosphorus(III)-based dications [RP(C(PPh3)2)](2+) (4a(2+), R = Ph; 4b(2+), R = 4-F-Ph) is reported. These dications were generated by reaction of the corresponding monocationic precursors with excess Na[BAr4(Cl)]. Evidence for the existence of transient dicationic species was obtained by trapping the dication 4a(2+) 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. |
