- 1. A compound of formula II ##STR432## wherein: R.sup.1 and R.sup.2 independently of one another are hydrogen, halogen, or are (C.sub.1 -C.sub.8)-alkyl, (C.sub.2 -C.sub.8)-alkenyl, (C.sub.2 -C.sub.8)-alkynyl or (C.sub.1 -C.sub.8)-alkoxy, each of which is unsubstituted or mono- or polysubstituted by halogen, or is mono- or disubstituted by (C.sub.1 -C.sub.4)-alkoxy or (C.sub.1 -C.sub.4)-alkylthio; or are --(CH.sub.2).sub.n --COOR.sup.11, where n is an integer from 0 to 2;
- R.sup.11 is hydrogen, or (C.sub.1 -C.sub.8)-alkyl, (C.sub.2 -C.sub.4)-alkenyl or (C.sub.2 -C.sub.4)-alkynyl each of which is mono- or polysubstituted by halogen or (C.sub.1 -C.sub.4)-alkoxy radicals;
- X is oxygen or sulfur; and
- a, b, c, d and e independently of one another are 0, 1 or 2, with the proviso that the sum of c, d and e is greater than or equal to 2.
- 2. A compound of formula II as claimed in claim 1 wherein:
- R.sup.1 and R.sup.2 independently of one another are hydrogen, halogen or (C.sub.1 -C.sub.4)-alkyl which is unsubstituted, mono- or polysubstituted by halogen or mono- or disubstituted by (C.sub.1 -C.sub.4)-alkoxy or (C.sub.1 -C.sub.4)-alkylthio;
- a and b independently of one another are 0, 1 or 2, but with the proviso that the sum of c, d and e is greater than or equal to 2 and less than or equal to 4; and
- X is oxygen.
