The Magic Salt Effects of Sodium Hexafluorophosphate

Abstract The Na+PF6− salt changes the course of reactions between neutral or ionic substrates. Examples of reactions include superoxide radical chemistry, disproportionation, and C[sbnd]H and C[sbnd]O bond activation. This special salt effect is usually quantitative and sometimes catalytic. When compared to other salts, Na+PF6− by far gives the most spectacular results, due to the small size of Na+ as compared to large organometallic cations.
