Insekten- und milbenabweisende Mittel

Compounds of the formula wherein R is H, Cl, or Me, R1 is H or an aliphatic hydrocarbon radical, R11 is H, an aliphatic hydrocarbon radical or an alkoxy radical, R111 is an aliphatic hydrocarbon radical, m is 1, 2, or 3, n is 0, 1 or 2, and p is 1 or 2, are produced either by reacting the appropriate bicyclic hydrocarbon isocyanates, carbamic acid chlorides, or carbamic acid esters with the appropriate amine or by reacting the appropriate bicyclic hydrocarbon amine with the appropriate carbamic acid chloride or isocyanate. An example describes the preparation of N-isobornyl-N1, N1-dimethyl urea from ethyl N-isobornyl carbamate and dimethylamine, the carbamate having been prepared by the reaction of camphene with urethane and boron trifluoride etherate in benzene.ALSO:Insect and mite repellent compositions contain as active ingredient at least one urea derivative of the formula wherein R is H, Cl, or Me, R\sv is H or an aliphatic hydrocarbon radical, R\yF is H, an aliphtic hydrocarbon radical or an alkoxy radical, R\yG is an aliphatic hydrocarbon radical, m is 1, 2, or 3, n is 0, 1, or 2 and p is 1 or 2 in admixture with a solid or liquid diluent or carrier optionally containing a surface-active agent. The compositions, or the active compounds alone, may be applied to human or animal skin, or clothes.
