Abstract

A newly synthesized copper aluminum fluoride of nominal composition CuAl 2F 8 exhibits excellent reactivity towards direct oxidative fluorination of aromatic compounds, as well as fluorodechlorination of chloroaromatics. The spent CuAl 2F 8 reagent can be regenerated by treatment with O 2 and HF, and the fluorination process has been demonstrated to retain high conversions through 20 reaction cycles. The main advantages of this new process ...
