摘要： The reaction of 2-mercapto-benzothiazole or -benzimidazole with .alpha.,.beta.-unsaturated carboxylic acids in a strongly acid reaction medium gives compounds of the formula I ##STR1## in which X is sulfur or NH, each radical R independently of one another is H, alkyl, halogenoalkyl, alkoxy, alkylthio, alkylsulfonyl, phenyl, alkylphenyl, phenylalkyl, cycloalkyl, halogen, NO.sub.2, CN, COOH, COOalkyl, OH or an amino or carbamyl group and R.sup.1, R.sup.2 and R.sup.3 independently of one another are H, alkyl, halogenoalkyl, hydroxyalkyl, alkoxyalkyl, carboxyalkyl, carboxyl or unsubstituted or substituted aryl or aralkyl, or R.sup.1 and R.sup.2 together are straight-chain or branched alkylene, which can be substituted by 1 or 2 carboxyl groups.
