Abstract
NEW MATERIAL:The compound of formula I (R<1>-R<4> are H, lower alkyl, lower haloalkyl or phenyl; X is H or halogen; Y is O or S; Z is O, S or -NH-). EXAMPLE:5-( O, O-diethyl-thiophosphoryloxy )-1-methyl-pyrazol-3-ylacetic acid ethyl ester. USE:Insecticidal and miticidal agent. PREPARATION:The objective compound can be produced by reacting a com pound of formula II (e.g. 1-methyl-5-oxo-2-pyrazolin-3-ylacetic acid ethyl ester) with a phosphoric acid chloride of formula III (e.g. O,O-diethyl thiophosphoryl chloride) in a solvent (preferably benzene, etc.) in the presence of an acid accep tor (e.g. sodium hydroxide) at -80 deg.C- room temperature for 1-5hr.
