Abstract (en)

[origin: WO9931036A2] The invention describes O-derivatives of halogenated diphenyl ether compounds of formula (1), in which R1 and R2 independently of one another are F, Cl or Br; Y is a radical of formula (1a); (1b); (1c); (1d); (1e) or (1f); R3 is C1-C22alkyl; C1-C22alkoxy; phenyl; phenyl-C1-C4alkyl; --(CH2)p4-A<+>R5R6R7; the radical of formula (I); R4 C1-C22alkyl; R5, R6, R7 and R8 independently of one another are hydrogen; C1-C4alkyl; sulfo-C1-C4alkyl; or R5 and R6 together with A form a cyclic radical unsubstituted or substituted by sulfo groups; or R7 and R8 together with N form a cyclic radical unsubstituted or substituted by sulfo groups; A is N or P; Z1 is fluorine, chlorine, the radical of formula (1g); Z2 is fluorine, chlorine, C1-C22alkoxy, C1-C22alkylthio or C1-C22-monoalkylamino or C1-C22dialkylamino; each of which is unsubstituted or substituted by OH, NH2 or sulfo; C6-C12aryloxy, C6-C12arylthio or C6-C12monoarylamino or C6-C12diarylamino, each of which is unsubstituted or substituted by OH, NH2 or sulfo; m is from 1 to 3; n is 1 or 2; and p1, p2, p3, p4 and p5 independently of one another are 1-4. The diphenyl ether derivatives according to the invention have excellent antimicrobial properties and are stable to migration.
