Efficient Method for Varying the Anions in Quaternary Onium Halides

Quaternary onium salts of halides can be efficiently converted into the corresponding quaternary onium salts of various anions [NO3–, BF4–, PF6–, CF3SO3–, CH3SO3–, ClO4–, p‐CH3C6H4SO3–, CF3CO2–, 2,4‐(NO2)2C6H3O–] by treating the onium halide with trimethyl phosphate under neat condition in the prese...

Description
Summary:Quaternary onium salts of halides can be efficiently converted into the corresponding quaternary onium salts of various anions [NO3–, BF4–, PF6–, CF3SO3–, CH3SO3–, ClO4–, p‐CH3C6H4SO3–, CF3CO2–, 2,4‐(NO2)2C6H3O–] by treating the onium halide with trimethyl phosphate under neat condition in the presence of an equivalent amount of conjugate acid of the desired anion. An efficient and scalable method for the conversion of quaternary onium halides into the corresponding salts of various anions [NO3–, BF4–, PF6–, CF3SO3–, CH3SO3–, ClO4–, pTsO–, CF3CO2–, 2,4‐(NO2)2C6H3O–] is disclosed.
