<p>Esters of phosphorus acids Compounds of type: where R' = 1-3C alkyl; R2 = 1-3C alkyl or 1-3C alkoxy R3 = 1-4C alkyl, R4 = 1-4C alkyl or allyl, X, Y = (the same or different) H, methyl or halogen; esp O, O-diethyl-O-(4-O-methylbenzaldoxime)-, (4-O-ethylacetophenonoxime)-, (4-O-methyl-2, 5-dichlorobenzaldeoxime)- and 4-O-allylbenzaldoxime)-thionophosphate are useful as insecticides and acaricides. They are prepd. by condensing R'OPR2SCl with the appropriate phenol in presence of an acid-binding compound.</p> |
