Abstract

Ferrocene derivatives of the formula ##STR1## IN WHICH R represents the group COOR.sup.1, in which PA1 R.sup.1 represents hydrogen, alkyl, one equivalent of an alkali metal, alkaline earth metal or heavy metal cation, or an ammonium cation in which one or more PA1 Hydrogen atoms can be replaced by alkyl, Or R represents the group COR.sup.2 in which PA1 R.sup.2 represents optionally substituted alkyl, optionally substituted alkenyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl or optionally substituted phenyl, Or PA1 R represents the group ##STR2## in which R.sup.3 represents hydrogen or alkyl and PA1 R.sup.4 represents a ureido or thioureido radical, a radical of the formula --CH.sub.2 --CH.sub.2 --N.dbd.CH--ferrocene, a 5-membered or 6-membered heterocyclic radical or a group of the formula --OR.sup.5 or --NH-R.sup.6, in which PA1 R.sup.5 represents hydrogen, alkyl, one equivalent of an alkali metal or alkaline earth metal cation, or an ammonium cation in which one or more hydrogen atoms canbe replaced by alkyl, and PA1 R.sup.6 represents aryl or a 5-membered or 6-membered heterocyclic radical, Or PA1 R represents the sulfonamide group or the radical --SO…
