Abstract:
Title compds. I(R = halo, C2-6 alkyl, C1-3 halogenoalkyl, NO2, C1-4 thioalkyl, OCH3; R1,R2,R3 = C1-6 alkyl; X = O, S; n = 1, 2, 3), useful as insecticides and nematocides, were prepd. by the reaction of compds, II and phosphorous compds. III(one of A and B is Cl or Br, the other SY; Y = H or metal cation). Thus, chloro acetylanilide II(A = Cl) and ammonium salt of phosphorous compds. III(B = SNH4) was stirred in glycolmethylether for 3-5 hr at 50≦̸C to give I.

Title compds. I (R= halo, C1-6 alkyl, C1-3 haloalkyl, C1-2 alkoxy, NO2; R1 = H, C1-6 alkyl; R2 = C1-6 alkylamino, C3-8 alkenylamino, C5-8 cycloalkylamino; X = O, S; n = 0-3 integer), useful as herbicides, insecticides, and nematocide, were prepd. by reaction of compds. II and phosphorous compds. III(one of A and B is halogen such as Cl, Br, the other SY(Y = H, metal cation). Thus, chloro acetanilide II (A = Cl) was mixed with ammonium salt (III; B = SNH4) of phosphorous compd. in glycoldimethylether for 3-5 hr at 50≦̸C to give I.
Abstract:
This invention is concerned with novel derivatives of 3-hydroxy2,2-dimethylpropanaloxime, viz, compounds of the general formula R-O-CH2-C(CH3)2-CH NO-CO-NHR1, of which R and R1 are defined in the specification. The novel compounds exert insecticidal properties.
WHERE R1 IS ALKYL OR ALKOXY EACH HAVING FROM 1 TO 4 CARBON ATOMS OR PHENYL; R2 IS ALKOXY HAVING FROM 1 TO 6 CARBON ATOMS IF R1 IS ALKYL OR PHENYL, AMINO, ALKYLAMINO OR DIALKYLAMINO EACH HAVING FROM 1 TO 6 CARBON ATOMS, OR ALKENYLAMINO HAVING FROM 1 TO 4 CARBON ATOMS; R3 IS HYDROGEN OR ALKYL HAVING FROM 1 TO 4 CARBON ATOMS; R4 IS HYDROGEN, ALKYL HAVING HAVING FROM 1 TO 4 CARBON ATOMS; OR HALOGEN; X IS OXYGEN OR SULFUR; ARE USEFUL PESTICIDES IN THE AGRICULTURAL AND VETERINARY FIELDS.
Abstract:
Compounds of the formula (I) in which R represents halogen, C1-C6-alkyl, C1-C3-haloalkyl, C1-C2 alkoxy, NO2 or S-CH3, R1 represents hydrogen or C1-C6-alkyl, R2 represents C1-C6-alkylamino, C3-C8-alkenylamino, N,N-di-(C1-C6-alkylamino), C5-C8-cycloalkylamino or a saturated N-heterocycle having from 4 to 8 C-atoms altogether of which 1 or 2 may stand in the side chain and in which one CH2group of the cycle may be replaced by oxygen or sulfur, R3 represents C1-C6-alkyl, X is oxygen or sulfur and n is zero or a whole number in the range of from 1 to 3 exhibit a good herbicidal effect on some economically important weed grasses and dicotyledonous weeds and simultaneously they have excellent insecticidal and acaricidal properties.
