Stabilization of the P(CF (sub)3) (sub)2 (super)- ion as a reversible CS (sub)2 adduct, [P(CF (sub)3) (sub)2 CS (sub)2] (super)-, and its potential use as a nucleophilic P(CF (sub)3) (sub)2 (super)- source: synthesis and structure of [18-crown-6-K][P(C (sub)6 F (sub)5) (sub)2 CS (sub)2]

Research has been conducted on the P(CF (sub)3) (sub)2 (super)- ion. The ability of this ion to stabilize in solution has been investigated and the results indicate that this feature can affect the ion's capability to be used in nucleophilic displacement reactions.
