Abstract
Substituted guanidine derivatives of the formula I ##STR1## are prepared by reacting calcium cyanamide with a primary or secondary amino carboxylic acid or a primary or secondary amino sulfonic acid or their derivatives of the formula II ##STR2## where the substituents R.sup.1 and R.sup.2 have the meanings explained in the description.
