Abstract

Fluorine-containing phenethylamines are obtained in an advantageous manner by reacting fluorine-containing bromobenzenes with acrylamide in the presence of a palladium catalyst, hydrogenating the resulting arylacrylamides catalytically and then rearranging the arylamides obtained. The invention also embraces novel arylacrylamides and novel arylamides.
