2,4-Difluorophenylboronic acid

چکیده
The mol-ecular structure of the title compound, C(6)H(5)BF(2)O(2), is essentially planar (mean deviation = 0.019 Å), indicating electronic delocalization between the dihydroxy-boryl group and the aromatic ring. In the crystal structure, inversion dimers linked by two O-H⋯O hydrogen bonds arise. An intra-molecular O-H⋯F hydrogen bond reinforces the conformation and the same H atom is also involved in an inter-molecular O-H⋯F link, leading to mol-ecular sheets in the crystal.

متن کاملMetabolism of 2,4-Dichlorophenoxyacetic Acid (2,4-D) in Soybean Root Callus : EVIDENCE FOR THE CONVERSION OF 2,4-D AMINO ACID CONJUGATES TO FREE 2,4-D.
An auxin-requiring soybean root callus metabolized [1-(14)C]-2,4-dichlorophenoxyacetic acid (2,4-D) to diethyl ether-soluble amino acid conjugates and water-soluble metabolites. The uptake in tissue varied with incubation time, concentration, and amount of tissue. Uptake was essentially complete (80%) after a 24-hour incubation and the percentage of free 2,4-D in the tissue fell to its lowest p...
متن کاملEffect of 2,4-Dinitrophenol on Auxin-induced Ethylene Production and Auxin Conjugation by Mung Bean Tissue.
Auxin-induced ethylene production by mung bean (Phaseolus mungo L.) hypocotyl segments was markedly inhibited by 2,4-dinitrophenol regardless of whether or not kinetin was present. Uptake of indoleacetic acid-2-(14)C was also inhibited in the presence of 2,4-dinitrophenol. Segments treated only with indoleacetic acid rapidly converted indoleacetic acid into indole-3-acetylaspartic acid with tim...
متن کاملAcute toxicity evaluation of five herbicides: paraquat, 2,4-dichlorophenoxy acetic acid (2,4-D), trifluralin, glyphosite and atrazine in Luciobarbus esocinus fingerlings
Background: Evaluation of herbicide pollution in aquatic environments needs the great concern and the most important echo-pollutant effects of herbicides are related to their effects on non target aquatic organisms. Native fish can serve as a proper bio-indicator for evaluation of pollution on aquatic ecosystems. OBJECTIVES: To find environmentally friendly herbicides, in this study the acute ...
متن کاملA comparison of 2,4-dichlorophenoxyacetic Acid metabolism in cultured soybean cells and in embryogenic carrot cells.
The removal or reduction in concentration of auxin is often a successful method for obtaining morphogenesis in cell cultures of higher plants, such as carrot, but not for soybean. For this reason, the metabolism of one auxin, 2,4-dichlorophenoxyacetic acid (2,4-D), was compared in both carrot and soybean cells. Whereas soybean cells conjugated a high percentage of their 2,4-D to amino acids, ca...
