Abstract
NEW MATERIAL:A phosphoric ester derivative of formula I (R1 is lower alkoxyl or phenyl; R2 is lower alkoxyl, lower alkylamino, phenylalkylmercapto, etc.; Y is O or S; R3 is H, lower alkyl, nitro, etc.; X is halogen).
EXAMPLE: O,O-Diethyl (5-chloro-2-methyl-γ-pyron-3-yl)-thiophosphate.
USE: An insecticide and acaricide effective against injurious insects and mites growing on the crops and sanitary injurious insects. Preferably, the pharmaceutical is diluted to contain about 0.0001W10wt% the active substance according to the purposes intended in use.
PROCESS: A compound of formula II is reacted with a compound of formula III (Hal is halogen in a solvent, e.g. dioxane, in the presence of an acid acceptor, e.g. NaOH or KOH, in a molar amount of about 0.5W3.0 times that of the compound of formula III to give the titled substance of formula I.
