ABSTRACT:
Compounds of the formula ##STR1## in which X is the radical ##STR2## where R.sub.1 and R.sub.2 are in each case a hydrogen atom, an alkyl-(C.sub.1 -C.sub.10) group, aryl group, alkyl(C.sub.1 -C.sub.6)-CO group or aryl-CO group, where the aryl or aryl-CO group in the case of R.sub.1 and R.sub.2 can be substituted on the aromatic ring by fluorine and/or chlorine atoms and/or alkyl(C.sub.1 -C.sub.4) groups, or R.sub.1 and R.sub.2 together are a phthaloyl radical which can be substituted on the aromatic ring by 4 chlorine atoms or 4 fluorine atoms, or where X is the radical ##STR3## which can be substituted on the aromatic ring by fluorine and/or chlorine atoms and/or alkyl(C.sub.1 -C.sub.4) groups, and processes for their preparation.
