摘要:
Cyanoisoxazoles of the formula Ia or Ib ##STR1## where R.sup.1 is hydrogen, alkyl, cycloalkyl, phenyl; R.sup.2 is hydrogen, alkyl, cycloalkyl and R.sup.3 is alkoxy, alkyl, cycloalkyl, cycloalkenyl, alkenyl, alkynyl or phenyl, it being possible for the organic radicals mentioned under R.sup.1, R.sup.2 and R.sup.3 to be substituted in each case.
