NEW MATERIAL:A phenoxypyrimidine derivative of formula I: [one of R1 and R2 is H, 1W4C lower alkyl group, or halogen and the other is group of formula II (R5 is 1W6C lower alkyl group; R6 is H or 1W4C lower alkyl group; n is 0,1, or 2); R3 and R4 are H, 1W4C lower alkyl, 1W4C lower alkoxy, nitro groups, or halogen].
USE: Acaricides for agriculture and horticulture particularly effective against eggs, also effective against plant lice, mosquitoes, flies, cockroach, etc. Herbicides effective against true grasses and broad leaf weeds.
PROCESS: A compound of formula III is reacted with a compound of formula IV in equimolar or slight excess of the compound III in the presence of a base, e.g. metallic sodium or potassium ethoxide to give the objective compound of formula I.
