<p>Novel compounds having the formula I (I) are described wherein x is a chlorine bromine or iodine atom and Y is a residue having the formula RIR2R3C- where n R and R are the same or different and each is a fluorine chlorine or bromine atom and R3 is a hydrogen,fluorine chlorine or bromine atom a group -CR R5P6 a cyano group, a group-COR7 or -Po(R8)2 wherein R R5 R6 independently, are F, Cl or Br R7 and R8 are the same or different and each is a chlorine atom or a group -oR9 wherein R9 is a Cl-C4 straight chain or branched alkyl group with the proviso that when X is chlorine- atom none of R1 R2 R3, R4 R5 and R6 can be a bromin atom They can be obtained by reacting dikecane with a compound XY in the presence of an agent capabl of forming free radical, Compounds have biocital aceivity against various organism, e,g, bacteria fungi and algae. They are paticularly suitable for antifoulant compositions.</p> |
