Polarization of xf bonds

Hydrolysis in the system LiPF6—propylene carbonate—dimethyl carbonate—H2O

“…It is known that the hydrolysis of other complexes of fluoro acids also involves H + ions, as well as the other polarizing cations [26][27][28][29][30][31]. In the recent works of Ponikvar et al [30,31], it was shown that hydrolysis of bonds to fluorine is often assisted by acids.…”

“…In the recent works of Ponikvar et al [30,31], it was shown that hydrolysis of bonds to fluorine is often assisted by acids. We suggest that lithium ions, located in the crystal lattice of solid LiF, i.e.…”

Substituent effects on proton affinities of simple molecules

“…Analogous O-F bond polarization has been invoked30 in a discussion of the reaction of OF2 with primary amines to form the corresponding knowledge, protonated F2 has not been proposed in the literature. We note, however, that protonated Cl2 and Br2 have recently been invoked in aromatic halo-genations50 and proton-polarized F2 in low-temperature olefin-fluorine reactions (ref 30 discussing the results in ref 51).…”
