Nematicidal activity of natural ester compounds and their analogues against pine wood nematode, bursaphelenchus xylophilus

In this study, we evaluated the nematicidal activity of natural ester compounds against the pine wood nematode, Bursaphelenchus xylophilus, to identify candidates for the development of novel, safe nematicides. We also tested the nematicidal activity of synthesized analogues of these ester compounds to determine the structure-activity relationship. Among 28 ester compounds tested, isobutyl 2-methylbutanoate, 3-methylbutyl 2-methylbutanoate, 3-methylbutyl tiglate, 3-methyl-2-butenyl 2- methylbutanoate, and pentyl 2-methylbutanoate showed strong nematicidal activity against the pine wood nematode at a 1 mg/ mL concentration. The other ester compounds showed weak nematicidal activity. The LC50 values of 3-methylbutyl tiglate, isobutyl 2-methylbutanoate, 3-methylbutyl 2-methylbutanoate, 3-methyl-2-butenyl 2-methylbutanoate, and pentyl 2- methylbutanoate were 0.0218, 0.0284, 0.0326, 0.0402, and 0.0480 mg/mL, respectively. The ester compounds described herein merit further study as potential nematicides for pine wood nematode control.

Kinetics of alcoholysis of β,β-dimethylacryloyl chloride

Rate constants and activation parameters have been determined for alcoholysis of β,β-dimethylacryloyl chloride with 14 alcohols in benzene at a reactant ratio of 1:1. The reaction proceeds via formation of H-complex or charge-transfer complex. Appropriate description of the effect of alcohol on the reaction rate requires simultaneous application of the Hammett-Taft and Koppel'-Pal'm equations.

Thermodynamic properties of the esters of 3-methyl-2-butenoic acid

The enthalpies of combustion of four esters of 3-methyl-2-butenoic acid were determined by bomb calorimetry. The temperature dependence of the saturated vapor pressure for the esters was studied with the tensimetry technique. The standard enthalpies of formation and vaporization for the esters were calculated.
