HALOGEN EXCHANGE REACTIONS AND USES THEREOF

A mixture of (i) finely-divided alkali metal fluoride (e.g., KF), (ii) haloaromatic compound having at least one halogen atom of atomic number greater than 9 on an aromatic ring (e.g., C6Cl6), and (iii) an aminophosphonium catalyst (e.g., Et2N)4PBr), is heated at a temperature at which fluorine repl...

Beschreibung
Zusammenfassung:	A mixture of (i) finely-divided alkali metal fluoride (e.g., KF), (ii) haloaromatic compound having at least one halogen atom of atomic number greater than 9 on an aromatic ring (e.g., C6Cl6), and (iii) an aminophosphonium catalyst (e.g., Et2N)4PBr), is heated at a temperature at which fluorine replaces one or more of the ring halogen atom of the haloaromatic compound. Processes are described wherein fluorinated perhalobenzenes such as C6ClF5 and C6BrF5 formed in this manner are converted efficiently and at low cost to a variety of industrially important products.
