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.
