Abstract
NEW MATERIAL:Thio or dithiophosphate esters of formulaI (R is alkyl; R1 is alkyl, phenyl, lower alkylamino, phenoxy, lower alkylmercapto; R2 is H, halogen; R3 is alkyl; X is O,S).
EXAMPLE: O-Ethyl-O-(2-methoxymethyl-6-methyl-pyrimidine-4-yl)benzenethiono- phosphonate ester.
USE: Insecticide, acaricide, and nematocide; especially it is effective against rice borers in paddies and further against mosquitoes and tetranychids.
PREPARATION: The condensation reaction between a compound of formula II and another compound of formula III (Hal is halogen) is effected in a solvent as acetone or others in the presence of an inorganic base as anhydrous potassium carbonate or organic base as pyridine, when necessary, copper dust or cuprous chloride at room temperature W100°C to give the compound of formula I.
