BORON CONTAINING COMPOUNDS AND THEIR USES
-
Paragraph 00254-00256; 00258, (2022/03/07)
The present disclosure relates to novel boron-containing compounds and their novel uses, e.g., as active ingredients that have pesticidal activity. The disclosure also relates to agrochemical compositions and their use in agriculture or horticulture for the control or prevention of infestation of plants, plant parts, plant propagation materials, harvested food crops, or seeds by pests, specifically fungi and nematodes. The disclosure further relates to methods for promoting plant performance and/or curatively or preventively controlling phytopathogens, (particularly fungi and nematodes) on or in a plant, plant parts, plant propagation materials, seeds, harvested fruits, or vegetables.

Functionalized 2-formylphenylboronic acids undergo an unprecedented tautomeric rearrangement in solution to form corresponding 1,3-dihydro-1,3- dihydroxybenzo[c][2,1]oxaboroles. X-Ray analyses of selected examples revealed diverse solid-state molecular structures from a planar open form with a hydrogen-bonded carbonyl group (X = 3-F) through a twisted conformer showing a weak carbonyl-boron interaction (X = 3,5-Br2) to a cyclic oxaborole derivative (X = 3-Br). Variable-temperature 1H NMR spectroscopy was used to determine equilibrium constants as well as enthalpies and entropies of tautomerization in a mixed solvent [D6]acetone-D2O (95:5). A computational approach to the process by DFT (B3LYP) and MP2 methods has also been performed. The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.
