Abstract
The invention relates to novel quinoxaline-2-yl ethenyl ketones, their preparation and compositions containing them. The novel quinoxaline-2-yl ethenyl ketones of the general formula I ##STR1## wherein R.sub.1 represents an aryl group or a heterocyclic group comprising one or more nitrogen and/or oxygen and/or sulfur atoms wherein both the aryl and heterocyclic groups are optionally substituted by one or more identical or different substituents, PA1 R.sub.2 stands for a hydrogen atom or a C.sub.1-4 alkyl group, are prepared by reacting an acetylquinoxaline derivative of the general formula II ##STR2## wherein R.sub.2 is as stated above, with an aldehyde of the general formula III EQU R.sub.1 --CHO (III) PA1 wherein R.sub.1 is as stated above. The novel compounds of the general formula I possess valuable antibacterial effect and promote the growth of animals. Thus, the novel compounds can be incorporated in animal feeds.
