Auxin Activity of Substituted Benzoic Acids and Their Effect
Summinary. Six dichloro-, 3 trichloro-, 2 triiodo-, and 3 heterosubstituted benzoic acids (amiben, dinoben, dicamba), and N-1-naphthylphthalamic acid have been tested for effects on growth and on polar auxin transport. Growth activity with and without kinetin was measured by effects on fresh and dry weights of 30-day cultures of fresh tobacco pith. Transport inhibition was measured by following...
متن کاملDiortho Substituted Phenoxyacetic Acids as Antiauxins.
This paper concerns a new class of antiauxins, substances in themselves devoid of activity in the Avena coleoptile section growth test but capable of antagonizing the growth promoting effects of both native and synthetic auxins. These compounds, to which antiauxin activity has not previously been ascribed, are the diortho substituted phenoxyacetic acids. To establish rigorously that a growth in...
متن کاملThe effect of substituted benzoic acids on adaptive enzyme formation in a Mycobacterium.
Certain Mycobacteriu form adaptive enzymes for the oxidation of benzoic acid (1). The oxidation proceeds through catechol and protocatechuic acid (2) and is thus similar to that in PseudomonasJEuorescens (3). Neither cyclohexanecarboxylic acid nor any substituted benzoic acid is oxidized by these Mycobacteria, but certain of these compounds can induce the organism to form adaptive enzymes for b...
متن کاملIridium-Catalyzed ortho-Arylation of Benzoic Acids with Arenediazonium Salts.
In the presence of catalytic [{IrCp*Cl2 }2 ] and Ag2 CO3 , Li2 CO3 as the base, and acetone as the solvent, benzoic acids react with arenediazonium salts to give the corresponding diaryl-2-carboxylates under mild conditions. This C-H arylation process is generally applicable to diversely substituted substrates, ranging from extremely electron-rich to electron-poor derivatives. The carboxylate d...
متن کاملAcidity of ortho-substituted benzoic acids: an infrared and theoretical study of the intramolecular hydrogen bonds.
The structures of ortho-substituted benzoic acids with substituents bearing hydrogen atoms (OH, NH2, COOH and SO2NH2) were investigated by means of IR spectroscopy and of density functional theory at the B3LYP/6-311 + G(d,p) level. All possible conformations, hydrogen bonds, tautomeric forms and zwitterions were taken into consideration and particular attention was given to intramolecular H-bon...
