Abstract

Novel asymmetric thioethers of the formula ##STR1## in which the general symbols have the following meanings: R.sup.0 represents hydrogen or C.sub.1-7 -alkanoyl, PA1 R.sup.1 represents C.sub.1-3 -alkyl which may be substituted by one or more halogen atoms having an atomic number of at most 17, PA1 R.sup.2 represents an aliphatic radical having from 5 to 15 carbon atoms, PA1 A represents ethylene, a single bond or vinylene, PA1 B.sup.1 represents C.sub.1-7 -alkylene or phenylene, PA1 B.sup.2 represents a single bond, ethylene or phenylene, and PA1 M represents an aromatic radical of the partial formula ##STR2## in which the symbols have the following meanings: R.sup.3 represents hydrogen or C.sub.1-4 -alkyl, PA1 X represents NH, O, S or if R.sup.4 represents hydrogen, a single bond, PA1 one of the symbols R.sup.4 and R.sup.5 represents hydrogen and the other represents the group --CO--R.sup.6, or PA1 R.sup.4 and R.sup.5 together represent the radical --CO--C(R.sup.6).dbd.C(R.sup.7)--or--CO--C(R.sup.7).dbd.C(R.sup.6)--or PA1 R.sup.4 R.sup.5, together with X, represent the radical --N.dbd.C(R.sup.8)--C(R.sup.6).dbd.CH--, in which PA1 R.sup.6 represents --(CH.sub.2).sub.b --COOR.sup.3 …
