Vanadium chloride and chloride oxide complexes in an ambient-temperature ionic liquid. The first use of bis(trichloromethyl) carbonate as a substitute for phosgene in an inorganic system

Abstract

The oxo exchange chemistry of vanadium chloride and chloride oxide complexes in solution in a room-temperature ionic liquid has been investigated, using a number of reagents. The structures of the solute species have been elucidated using a combination of electronic absorption spectroscopy and extended X-ray absorption fine structure. The reagent bis(trichloromethyl) carbonate has been used as a substitute for phosgene (COCl₂) in an inorganic system for the first time.
