ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to novel aminophosphonium compounds, to substance mixtures containing them, and to the preparation and use thereof.
Aminophosphonium compounds are used, as is evident from WO 98/32532 and WO 98/22413, as catalysts for preparing fluorine-containing compounds by a halogen/fluorine exchange reaction (halex reaction). Although the tetrakis(diethylamino)phosphonium bromide used in WO 98/32532 and WO 98/22413 gives good results, it has a very high dermal toxicity which stands in the way of industrial use, however.
SUMMARY OF THE INVENTION
The object is to provide novel compounds which are suitable as catalyst or component of catalyst systems for phase-transfer reactions, in particular for halogen-fluorine exchange reactions, have a lower dermal toxicity and achieve or even exceed the results obtainable on use of tetrakis(diethylamino)phosphonium bromide.
