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 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 کاملStructural landscape of benzoic acid: using experimental crystal structures of fluorobenzoic acids as a probe.
Experimental crystal structures of mono and polyfluorinated benzoic acids correspond to high energy computed crystal structures of benzoic acid itself, thereby permitting access to its structural landscape.
متن کاملCrystal structures of two substituted thiazolidine derivatives
In the first of the compounds reported herein, namely 6'-ferrocenyl-6a'-nitro-6',6a',6b',7',9',11a'-hexa-hydro-2H-spiro-[ace-naphthyl-ene-1,11'-chromeno[3',4':3,4]pyrrolo-[1,2-c]thia-zol]-2-one, [Fe(C5H5)(C29H21N2O4S)], (I), the thia-zolidine ring adopts a twist conformation on the methine N-C atoms. In the second compound, viz. 6'-(4-methoxy-phen-yl)-6a'-nitro-6',6a',6b',7',9',11a'-hexa-hydro-...
متن کاملHighly efficient and enantioselective hydrogenation of quinolines and pyridines with Ir-Difluorphos catalyst.
The combination of the readily available chiral bisphosphine ligand Difluorphos with [Ir(COD)Cl](2) in THF resulted in a highly efficient catalyst system for asymmetric hydrogenation of quinolines at quite low catalyst loadings (0.05-0.002 mol%), affording the corresponding products with high enantioselectivities (up to 96%), excellent catalytic activities (TOF up to 3510 h(-1)) and productivit...
