The invention concerns a process for killing internal parasites, especially trematodes or nematodes, affecting warm blooded animals such as cattle, sheep and goats by administering an effective amount of a composition containing as active ingredient a compound of the formula ##STR1## Certain of the compounds of formula I are novel and in further embodiments the invention provides novel compounds and compositions for use in the process of the invention. The process of the invention is especially applicable to the tretment of warm blooded animals infected with the trematodes Fasciola hepatica (liver fluke).

5-Substituted pyrimidine derivatives active against internal animal

The invention concerns novel compounds of the formula I ##STR1## wherein A, B, D and E are chosen from hydrogen, halogen, C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 haloalkyl and C.sub.1 to C.sub.6 alkoxy and Z is a tertiary or quaternary amino group. The compounds are useful intermediates for the preparation of pyrethroids. In further embodiments the invention provides processes for the preparation of the compounds of formula I and processes for the synthesis of pyrethroids utilizing the compounds of formula I.

Cyanophenoxybenzyl amines

A method for killing internal parasites of warm blooded animals by treating the animals with an effective amount of a composition comprising a bis-(2-hydroxy-3-nitrophenyl)methane derivative; and novel bis(2-hydroxy-3-nitrophenyl)methane derivatives.
