PURPOSE: To provide the subject novel compound useful as an intermediate for active compounds for controlling pests of animals, arthropods and nematodes, especially insects and arachnids in the fields of protection of sanitation of agri cultural products, forests and stored substances and materials.
CONSTITUTION: There is provided an o-phenylenediamine of formula I [wherein R1 is CF3, OCF3, SCF3, an SO2-1-6C alkyl, N(CF3)2, phenyl or phenoxy (containing CF3 or CN in position 4); R2 is F, Cl, Br, CN, CH3, OCF3, an SO2-1-6C alkyl, a COO-1-6C alkyl, 1,1,2,2-tetrafluoroethoxy or the like; R3 is H, COCH3, COCF3; and R1 and R2 may be combined with each other to form -O-CFCl-CFCl-O-, provided that compounds of EP-A251013 and EP-A487286 are excluded]. It is exemplified by 2-bromo-4,5-diamino-(1,1,2-trifluoro-2-chloro) ethoxybenzene. A compound of formula I can be obtained for example by dinitrating a benzene derivative of formula II (wherein D1 is CF3O or the like; and D2 is CF3D or the like) and reducing the nitro groups of the compound.
