Low-temperature fluorination routes have been successfully employed to control the transition metal oxidation state in a range of systems, leading to an ability to manipulate the electronic and magnetic properties. Following on from the initial studies on the use of F2 gas to introduce superconductivity in cuprate systems, such as La2CuO4 and Sr2CuO3, such studies have been extended to other transition metal oxide systems. In addition to the use of F2 gas, further studies have targeted the use of alternative solid-state fluorinating reagents, with a view to more accurately controlling the F content. In this chapter we will illustrate the work performed using the different fluorinating reagents, highlighting their advantages and disadvantages.
