During plant-microbe interactions and in the environment, Xanthomonas campestris pv. phaseoli is likely to be exposed to high concentrations of multiple oxidants. Here, we show that simultaneous exposures of the bacteria to multiple oxidants affects cell survival in a complex manner. A superoxide generator (menadione) enhanced the lethal effect of an organic peroxide (tert-butyl hydroperoxide) ...

In the title compound, C9H13NO2S, the dihedral angle between the thiophene ring and the carbamate group is 15.79 (14)°. In the crystal structure, intra-molecular C-H⋯O inter-actions in tandem with the tert-butyl groups render the packing of adjacent mol-ecules in the [001] direction nearly perpendicular [the angle between adjacent thio-phene rings is 74.83 (7)°]. An inter-molecular N-H⋯O hydrog...

Near-infrared absorbing aza-BODIPYs with 1,7-di- tert -butyl groups (tBuazaBDP) were successfully synthesized.

the acute intravenous toxicities of a selection of three potential long-acting local anaesthetics belonging to the series of2- phenoxyethyldialkylamine were determined in mice. two of the compounds were tertiary amines and the third a quaternary ammonium derivative.the i.v. median lethal dose, (ldso) of one of the tertiary compounds, 21a [n, n- diethyl-2- (2,6- diisopropyl) ethyl amine hydrochl...

The adsorption of methyl tert-butyl ether by granular activated carbon was investigated. The experimental data were analyzed using the Freundlich isotherm and the Langmuir isotherm. Although equilibrium data were found to follow Freundlich isotherm model, it were fitted better by the Langmuir model with a maximum adsorption capacity of 204.1 mg/g. The kinetic data obtained at different concentr...

The title compound, C(24)H(41)NO, is a new derivative of the anti-HIV steroid 17β-(N-tert-butyl-amino-carbon-yl)androst-4-en-3-one. There are four rings in the structure and these are trans-fused. The three six-membered rings exhibit chair conformations, while the five-membered ring adopts an envelope conformation.

The paper complements our earlier NMR investigation of molecular dynamics of tert-butyl chloride restricted by geometries of the type MCM-41 and CPG by the new sizes of CPG and by differential scanning calorimetry method. We report proton and deuteron NMR lineshapes and the spin-lattice relaxation results of tert-butyl chloride in CPG of the 15.6 nm and 7.4 nm pore diameter in the temperature r...

The effect of concentration, molar ratios of reagents, pH, and temperature on formation of chloro-organic products in reaction of tert-butyl ethers with chloride ions and hydrogen peroxide has been determined. A significant effect of Cl(-) ions and H(2)O(2) molar ratios on the rate of chloro-organic product formation has been observed. Studies on oxychlorination of tert-butylethyl ether (ETBE) ...

Multicobalt(II) two-dimensional layer coordination polymer {[Co(bitbu-OMe)2(NCS)2]·2MeOH}n (1) was synthesized using a bis-imidazole ligand having steric hindrance, tert-butyl, and one methoxy group expressed by bitbu-OMe (bitbu-OMe = 1,1′-[(5-tert-butyl-2-methoxybenzene-1,3-diyl)dimethanediyl]bis(1H-imidazole). Since there are two methanol molecules trapped inside each void within 1, the inves...
