    Abstract: Compounds of the formula I in which R1 denotes hydrogen or (C1-C6)-alkyl, optionally substituted by halogen or a hydroxyl group, R2 denotes hydrogen, (C1-C6)-alkyl, or halogen, X denotes oxygen or sulphur and R3 denotes (C1-C20)-alkyl, which can be mono- or polysubstituted by hydroxyl, halogen, amino, (di)-(C1-C4)-alkylamino, (C1-C4)-alkoxy, (C1-C4)-haloalkoxy, (C1-C4)-alkoxy-(C1-C4)-alkyleneoxy, (C1-C4)-alkylthio which can be substituted by (C1-C3)-alkyl, halogen or (C1-C3)-haloalkyl, or can be substituted by (C1-C4)-alkylsulphinyl, (C1-C4)-alkylsulphonyl, trimethoxysilyl, amidocarbonyl, (C1-C4)-alkylsulphonyloxy, (C1-C6)-alkylcarbonyl, (C1-C6)-alkoxycarbonyl, (C1-C6)-alkylcarbonyloxy, cyano, thiocyano, (C3-C8)-cycloalkyl, which can be substituted by hydroxyl or (C1-C4)-alkylcarbonyloxy, aryl, aryloxy, arylthio, arylsulphinyl, arylsulphonyl, arylsulphonyloxy or arylcarbonyl, all of which can be substituted by (C1-C4)-alkyl, (C1-C4)-alkoxy or halogen, with the proviso that if the (C1-C20)-alkyl radical is substituted by substituted or unsubstituted aryl or aryloxy, hydroxyl additionally substitutes this alkylene moiety, have advantageous insecticidal, acaricidal, nematocidal or fungicidal properties.

    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.
