Triphenylmethyl fluoride as a fluorinating agent in phosphorus-halogen chemistry
Triphenylmethyl fluoride 1 will effect chlorine-fluorine exchange in certain phosphorus chlorides. Exchange of chlorine for fluorine was observed only in σ3λ3 (P)- and σ5λ5 (P)-compounds, while phosphorus oxychloride as an example of a σ4λ5 (P)-compound was unreactive towards 1.
