Compounds of the general formula
wherein R1, R2, R'. R4 and R5 are each independently H, Cl, Br. NO2 or CF3; X = H or Br; and Z is H, CH3 or CF3.
The compounds are all potent inhibitors of oxidative phosphorylation in rat liver mitochondria and have other biological activity, for example, insecticidal activity.
The compounds are made (A) where X = H and Z = CF3. by reacting the appropriately substituted phenylhydrazine with hexafluoroacetone in a basic organic solvent in the presence of an acidic dehydrating agent; (b) where X = H and Z is H or CH3 by reaction of the phenylhydrazine with 1,1,1-trifluoroacetone or trifluoroacetaldehyde in a suitable solvent in the presence of an acid catalyst: (c) where X = Br can be made from the corresponding compound where X = H by direct bromination.
The invention includes insecticidal compositions containing the compounds.
