Compounds of formula (I) are pesticides having activity against arthropods:
wherein R', R' and R' are H, alkyl, alkoxy, halo, cyano or trifluoromethyl, or two of R1, Rand R3 are linked to form a 3 or 4 carbon atom group;
X is 0 or NA where A is H or alkyl;
RisHoralkyl;
and R' and R' are H, alkenyl or haloalkenyl or optionally substituted alkyl, aryl or aralkyl, or NR'R' represents a heterocyclic ring; or an acid addition salt thereof.
The invention further provides methods for the preparation of the compounds, pesticidal formulations containing them, and their use in controlling arthropod pests.
