Uses

Triphenylcarbenium hexafluorophosphate is a reagent involved in Si-H and Si-Si bond activation at Pt of neutral and cationic silyl Pt bisphosphine complexes. It is used in investigations of interactions with chromium acetylacetonate nitride mononuclear complexes. It is used in double ring-opening polyaddition of spiro orthoesters. It is used as reagent in Synthesis of "push-pull" tropylium-fused aminoporphyrazine, Preparation of cycloheptatrienyl and tropylium calix[4]arenes, Synthesis of palladacycles containing chiral rhenium half-sandwich complex for use as a catalyst.

Lewis Acid Catalyzed Synthesis of Cyanidophosphates

Salts containing new cyanido(fluorido)phosphate anions of the general formula [PF6-n(CN)n]- (n=1-4) were synthesized by a very mild Lewis-acid-catalyzed synthetic protocol and fully characterized. All [PF6-n(CN)n]- (n=1-4) salts could be isolated on a preparative scale. It was also possible to detect the [PF(CN)5]- but not the [P(CN)6]- anion. The best results with respect to purity, yield, and low cost were obtained when the F-/CN- substitution reactions were carried out in ionic liquids. Cyanido(fluorido)phosphates: Salts containing [PF6-n(CN)n]- (n=1-4) ions were isolated on a preparative scale by utilizing Lewis acids (LA) catalysts under mild conditions (see equation). The best results with respect to purity, yield, and low cost were obtained when the F-/CN- substitution reactions were carried out in ionic liquids.

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.
