Abstract The N-(N′,N′,N″,N″-tetramethyl)guanidinyl substituted phosphines 1, boron trifluoride and antimony pentachloride. Instead of the expected Lewis acid-base adducts the phosphonium compounds 3-5, followed by the formation of the σ3 Pσ4 P+-phosphonium compound 3, leading to the chlorophosphonium hexachloroantimonates 4, and 5.
