Synthesis and herbicidal activity of new oxazinone herbicides with a long-lasting herbicidal activity against Echinochloa oryzicola

Chemical modification of the herbicide 1-[2-(benzothiazol-2-yl)isopropyl]-4-methyl-3-phenyl-5H-pyrrolin-2-one (MI-2826) has revealed a new oxazinone herbicide, 3-[2-(7-chlorobenzothiazol-2-yl)isopropyl]-2,3-dihydro-6-methyl-5-phenyl-4H-1,3-oxazin-4-one (MI-3069), for use in paddy fields. In comparing the phyototoxicity of the two herbicides to transplanted rice, the latter was superior to the former and kept the same predominant characteristic to control Echinochloa oryzicola Vasin for a long period of time owing to its long-lasting residual effect.

Dicumyl Peroxide used as curing Agent for different Types of Rubber Matrices Part I: Effect of Temperature

Several elastomers were cured with dicumyl peroxide at different vulcanization temperatures. The focus of the work was the investigation of the influence of curing temperature on curing characteristics of rubber compounds. Subsequently, crosslink density and physical mechanical properties of vulcanizates were evaluated. The results demonstrated that higher curing temperatures lead to a total acceleration of cross-linking process. The effect of temperature on the crosslink density was low and was dependent on the structure of tested rubbers. Physicalmechanical properties of vulcanizates were almost not influenced by curing temperature.

Alkyne 1,1-Hydroboration to a Reactive Frustrated P/B-H Lewis Pair

The Mes(2)P-C equivalent to C-SiMe3 alkyne reacts with the borane H2B-Fmes by means of a rare 1,1-hydroboration reaction to give an unsaturated C-2-bridged frustrated P/B-H Lewis pair. Most of its reactions are determined by the presence of the B-H functionality at the FLP function and the activated connecting carbon-carbon double bond. It reduces carbon monoxide to the formyl stage. With nitriles it reacts in an extraordinary way: it undergoes a reaction sequence that eventually results in the formation of a P-substituted dihydro-1,2-azaborole derivative. Several similar examples were found. In one case a P-ylide was isolated that was related to an intermediate of the reaction sequence. It subsequently opened in an alternative way to give an alkenyl borane product.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 3446-89-7. Formula: https://www.ambeed.com/products/3446-89-7.html.

A loop resonator for slice-selective in vivo EPR imaging in rats

A loop resonator was developed for 300 MHz continuous-wave electron paramagnetic resonance (CW-EPR) spectroscopy and imaging in live rats. A single-turn loop (55 mm in diameter) was used to provide sufficient space for the rat body. Efficiency for generating a radiofrequency magnetic field of 38 mu T/W-1/2 was achieved at the center of the loop. For the resonator itself, an unloaded quality factor of 430 was obtained. When a 350 g rat was placed in the resonator at the level of the lower abdomen, the quality factor decreased to 18. The sensitive volume in the loop was visualized with a bottle filled with an aqueous solution of the nitroxide spin probe 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy (3-CP). The resonator was shown to enable EPR imaging in live rats. Imaging was performed for 3-CP that had been infused intravenously into the rat and its distribution was visualized within the lower abdomen. (c) 2007 Elsevier Inc. All rights reserved.

TBHP/TBAI-Mediated Oxidative Cascade Reaction Consisting of Dimerization, Cyclization, and 1,2-Aryl Migration: Metal-Free Synthesis of Pyrrolin-4-ones and Highly Substituted Pyrroles

Treatment of enamino esters with TBHP (t-butylhydroperoxide) and TBAI (t-butylammonium iodide) in HFIP (hexafluoroisopropanol) was found to afford a variety of substituted pyrrolin-4-one compounds. This metal-free oxidative cascade reaction consists of the key steps of coupling of two radical intermediates, an intramolecular ring closure, and an exclusive 1,2-aryl radical migration. Upon treatment with a base, the obtained pyrrolin-4-ones could be converted to the highly substituted pyrrole compounds.

Can Medical-Grade Gloves Provide Protection after Repeated Disinfection?

The advent of the COVID-19 pandemic has generated an increased consumption of personal protective equipment (PPE), including gloves and masks, by healthcare workers and by the general public at a global scale. This has generated substantial shortage of these single-use and disposable PPEs that will end up as a landfill waste. Extending the life cycle of PPEs, such as gloves, by disinfecting treatments could help mitigate these concerns. However, the effect of various disinfection treatments on the functionality of gloves is unknown. In this study, six commonly used viral disinfection treatment methods (i.e., ultraviolet (UV) radiation, dry heat, steam, alcohol, chlorine compounds, and quaternary ammonium compounds) were evaluated for their effect on the performance attributes of two commonly used medical-grade gloves and nitrile and vinyl (latex) gloves. The barrier properties of both gloves against water and ethanol vapor flux were not affected up to 10 cycles of disinfection cycles. However, the increase in the disinfection cycle from 10 to 20 slightly reduced their barrier properties with minor variation in the type of disinfection and glove type. Infrared spectroscopy and microscopy investigations confirmed that both types of gloves could withstand up to 20 cycles of disinfection treatments with no observable change in the chemical structure and surface morphology of the disinfected surfaces, respectively. Lastly, tear property testing of the gloves indicated little to no change from the baseline after 20 cycles of treatment in both the nitrile and vinyl-based gloves. Overall, this study indicated that alcohol, UV, and heat treatment could be acceptable disinfection methods that allow the reuse of gloves up to 20 cycles. Such repeated disinfection of gloves not only reduces the strain on the supply of gloves but also decreases the postconsumer landfilled waste and environmental footprint of gloves.

Morphology evolution, mechanical properties, Mullins effect, and its reversibility of polylactide/nitrile butadiene rubber thermoplastic vulcanizates plasticized by dioctyl phthalate

Thermoplastic vulcanizates (TPVs) based on polylactide (PLA)/nitrile butadiene rubber (NBR) blends were prepared by dynamic vulcanization where the PLA phase was plasticized by dioctyl phthalate (DOP), and the influence of DOP dosage on mechanical properties, morphology evolution, Mullins effect, and its reversibility were investigated systematically. The experimental results indicated that the mechanical properties of PLA/NBR TPVs were improved significantly with the addition of DOP. Compared with that of the PLA/NBR TPVs, the Shore A hardness was decreased obviously, while the elongation at break was increased slightly with increasing DOP dosage. Mullins effect results showed that the TPVs incorporated with DOP had the relatively lower stress-softening effect. The recovery ability of the maximum stress could be remarkably enhanced by increasing heat treatment temperature. Morphology studies showed that the network microstructure of the co-continuous phases was denser with the increasing dynamic vulcanization time; however, the network microstructure of the co-continuous was changed slightly with the addition of DOP.

Targeted development of hydrophilic porous polysulfonamide gels with catalytic activity

We report the use of a template and functional monomers in the synthesis of three novel polysulfonamide gels with new architectures and functional groups. These mesoporous polysulfonamide gels were prepared by the condensation polymerization of benzene-1,3-disulfonyl chloride (as the main precursor), linear monomers, and cross-linkers (as variable precursors) in the presence of a silica template by a combination of sol-gel chemistry and the nanocasting technique. In this synthesis pathway, in situ polymerization onto the template surface led to the construction of a silica/polymer nanocomposite. Next, after removal of the template, the nanocomposite gels were transformed into mesoporous polysulfonamide nanospheres. After the physicochemical identification of the synthesized materials, functionalized polysulfonamides were used as reusable novel catalysts with high efficiency for the Strecker reaction under mild conditions. These polymers have Brunsted/Lewis acid active sites, a mesoporous structure, and hydrogen bonding. Moreover, since these polymers are hydmgels that can absorb water, they can promote the Strecker reaction through chemical absorption of the generated water as a driving force. Overall, this article describes a novel synthesis procedure and application of porous polysulfonamide gels.
