Kinetics of the reactions of the title compound with some amines as nucleophiles in aprotic solvents have been investigated at the λmax of the aminolysis product at 35 ± 0.1 °C under pseudo-first order conditions. The reaction is overall second order, first with respect to each reactant. The second order rate coefficients decreased with increase in [amine] in all cases. Formation of an electron donor-acceptor complex is indicated. The temperature effect on the reaction rate has been studied in the range (293-318 K). The entropy of activation parameters are large and negative in all cases indicating formation of a crowded transition state. Mechanistic interpretation is given.

New oxime ethers and pesticidal and herbicidal preparations containing them are disclosed. The oxime ethers correspond to the formula SPC1 Wherein R1 is a hydrogen atom or a lower alkyl radical; R2 is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical; or wherein R1 and R2 form part of a saturated or unsaturated carbocycle or a 5-, 6- or 7-membered heterocycle; R3 is nitro, trifluoromethyl, formyl, lower carbalkoxy, sulfamyl or mono- or di-lower alkyl fulfamyl radical; R4- and R5 each is a hydrogen or halogen atom, an amino, mono- or di-lower alkyl amino, lower alkoxy, cycloalkoxy, lower alkylthio, nitro, lower carbalkoxy, arylthio, lower aralkylthio or lower alkyl group, or 5-, 6- or 7-membered heterocycle.
