摘要: 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.

摘要: Known (R)-1-aryl-alkylamines of the formula ##STR1## in which R.sup.1 and Ar have the meanings indicated in the description, are prepared by a new process, which comprises a) reacting a racemate of an ethyl or methyl 2-aryl-alkanoate of the formula ##STR2## with ammonia in the presence of a lipase which is suitable for the cleavage of esters, in the presence of a diluent, b) separating off from the reaction mixture the resulting (R)-2-aryl-alkanamide of the formula ##STR3## and then reacting it with sodium hypochlorite or sodium hypobromite in the presence of water.

摘要: A novel synthesis of aromatic tertiary amines involves reacting an aromatic anil and an aromatic ether in a molar ratio of 1:1; adjusting the ratio to 2:1 produces novel enamines and by employing a two step process for enamine production, various unsymmetrically substituted enamines can be obtained which are readily hydrolyzed to corresponding deoxybenzoins which in turn are readily oxidized to benzils, the aromatic tertiary amines may be used to produce charge transport layers in xerography, while the benzils may be used to produce a variety of desired polymers.
