    Abstract: 1391398 Phosphorus-containing thiochromanone oxime derivatives HOECHST AG 23 March 1973 [24 March 1972] 14204/73 Heading C2P The invention comprises compounds of the general formula wherein R 1 is O-alkyl, NH-alkyl or N,N-dialkyl, R 2 is alkyl, O-alkyl or phenyl, the alkyl group in each of R 1 and R 2 having from 1 to 10 carbon atoms, R 3 and R 4 are selected from H or C 1 -C 4 alkyl, R 5 , R 6 , R 7 and R 8 are selected from H, halogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, and alkylthio and X is O or S. They are obtained by reacting a halide: Hal-P(X)(R 1 )(R 2 ) where Hal is halogen with a thiochromanone oxime of the formula in the presence of an acid binding agent or in the form of its salt. They may also be obtained by reacting the oxime (III) with a dihalide: (Hal) 2 P(X)R 1 or (Hal) 2 P(X)R 2 where R 1 is as defined above and R 2 is C 1 -C 10 alkoxy to form the corresponding diester monohalide or ester amide monohalide and then reacting the monohalides with an alcohol or amide (R 1 H) or with an alcohol (R 2 H) as appropriate. The products have pesticidal properties and may be used as active ingredients in conventional pesticidal compositions.
