And the article contained the following:

A highly efficient aromatic chlorination of arenes such as 1-methyl-indazole, imidazo[1,2-a]pyrazine, phenylthiophene, anthracene, etc. that is catalyzed by DMSO with N-chlorosuccinimide as the chloro source is reported. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, e.g., papaverine, drugs, e.g., diclofenac and peptides, e.g., I. The multi-gram experiment and low-cost of N-chlorosuccinimide and DMSO show great potential for drug discovery and development in industrial applications. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Synthetic Route of 91-16-7

And the article contained the following:

Heterogeneous single-site catalysts can combine the precise active site design of organometallic complexes with the efficient recovery of solid catalysts. Based on recent progress on homogeneous thioether ligands for Pd-catalyzed C-H activation reactions, a scalable metal-organic framework-based heterogeneous single-site catalyst containing S,O-moieties that increase the catalytic activity of Pd(II) for the oxidative alkenylation of arenes has been developed. The structure of the Pd@MOF-808-L1 catalyst was characterized in detail via solid-state NMR spectroscopy, N2 physisorption, and high-angle annular dark field scanning transmission electron microscopy, and the structure of the isolated palladium active sites could be identified by X-ray absorption spectroscopy. A turnover frequency (TOF) of 8.4 h-1 was reached after 1 h of reaction time, which was 3 times higher than the TOF of standard Pd(OAc)2, ranking Pd@MOF-808-L1 among the most active heterogeneous catalysts ever reported for the nondirected oxidative alkenylation of arenes. Finally, the single-site catalyst promotes the oxidative alkenylation of a broad range of electron-rich arenes, and the applicability of this heterogeneous system was demonstrated by the gram-scale synthesis of industrially relevant products has been reported. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Safety of 1,2-Dimethoxybenzene

On October 4, 2022, Zhang, Hao-Ran; Feng, Cong-Cong; Chen, Ning; Zhang, Song-Lin published an article.Application of 91-16-7 The title of the article was Direct Arene Trifluoromethylation Enabled by a High-Valent CuIII-CF3 Compound. And the article contained the following:

Direct C-H trifluoromethylation of arenes and heteroarenes poses an important synthetic challenge that is highly desirable. High-valent CuIII-CF3 compounds have often been invoked in copper-mediated trifluoromethylation reactions, but the fundamental reactivity toward arenes is elusive. Herein, direct C-H trifluoromethylation of arenes/heteroarenes by a high-valent CuIII-CF3 compound is disclosed for the first time. The CuIII-CF3 compound serves CF3 radical and a CuII oxidant by homolytic cleavage of a CuIII-CF3 bond, which engage synergistically in a SEAr type reaction with arenes. The presence of K2S2O8 co-oxidant can significantly improve the reaction yields. This reaction shows good efficiency, broad functional group tolerance, and the potential in late-stage functionalization. The reactivity of high-valent CuIII-CF3 compounds disclosed in this study represents an important progress in organofluorine and CuIII chem. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Application of 91-16-7

Here, a mild and practical method that allows for the direct C-H trifluoromethylation, perfluoroalkylation, and chlorodifluoromethylation of (hetero)arenes such as mesitylene, 1-tosyl-1H-pyrrole, N-(thiophen-3-yl)acetamide, etc. using TFA and the related carboxylic acids RC(O)OH (R = CF3, C5F11, CF2Cl, etc.) was reported. A diverse array of arenes and heteroarenes was successfully transformed into valued fluoroalkylated compounds e.g., I. The combination of photoredox catalysis and a bis(4-chlorophenyl) sulfoxide provides a platform for the facile generation of fluoroalkyl radicals from the corresponding fluoroalkyl carboxylic acids under mild conditions.

Ken; Little, Marc A.; Cooper, Andrew I. published an article.Reference of 1,2-Dimethoxybenzene The title of the article was An Expandable Hydrogen-Bonded Organic Framework Characterized by Three-Dimensional Electron Diffraction. And the article contained the following:

A mol. crystal of a 2-D hydrogen-bonded organic framework (HOF) undergoes an unusual structural transformation after solvent removal from the crystal pores during activation. The conformationally flexible host mol., ABTPA, adapts its mol. conformation during activation to initiate a framework expansion. The microcrystalline activated phase was characterized by three-dimensional electron diffraction (3D ED), which revealed that ABTPA uses out-of-plane anthracene units as adaptive structural anchors. These units change orientation to generate an expanded, lower d. framework material in the activated structure. The porous HOF, ABTPA-2, has robust dynamic porosity (SABET = 1183 m2 g-1) and exhibits neg. area thermal expansion. We use crystal structure prediction (CSP) to understand the underlying energetics behind the structural transformation and discuss the challenges facing CSP for such flexible mols.

Black truffle (Tuber melanosporum Vitt) is a fine agro-food product known for its unique aroma and very limited shelf life (maximum of 5-7 days, room temperature). Hypobaric packaging at 30 kPa, a mix of 1% O2/99% N2, and 40% CO2/60% N2 were studied to prolong the shelf life of black truffle at 4掳C in sealed polypropylene vessels, compared to normal atm. Epiphytic microbial population, firmness, weight loss, CO2 formation, and sensory properties were monitored weekly up to 35 days of storage and were related to the volatile profile. Principal components anal. revealed good correlation between the storage time and the decrease of firmness, and the increase of the microbial count and CO2 production Only truffles stored under hypobaric conditions showed an acceptable quality after 14 days storage. Hypobaric packaging is a cheap strategy to prevent the swelling of vessels caused by respiration and can reduce the deviation from the high-quality level of the fresh product from one to at least two weeks.

Aging is an essential step for enriching the aroma profiles of Chinese vinegar. This study aimed to track the volatile flavor changes in the same batch of Chinese vinegar for the first time during two years of aging with the aid of HS-SPME-GC-MS. The aroma-active compounds were characterized at 0, 6, and 12 mo of aging using GC-O coupled with a modified frequency method. A total of 67 volatile compounds and 30 aroma-active compounds were identified during the different stages of aging. Most alcs., esters, ketones, acids, and phenols decreased during the aging from 628.4, 105.4, 132.1, 22.1, and 21.4渭g/L at 0 mo to 228.7, 7.2, 9.69, 17.24, and 11.6渭g/L at 24 mo sep., except aldehydes and pyrazines, which showed slight increases. Many aroma-active compounds were generated during the aging, such as methional, trimethylpyrazine, acetophenone, and 2-acetyl-3-ethylpyrazine, while pyrazines were formed during 24 mo of aging. Three aroma-active compounds with high odor activity values (OAVs) showed significant contributions to the aroma profile of vinegar, which included isovaleric acid (2743, 340, and 3139), 4-ethylguaiacol (580, 429, and 516), and �nonalactone (324, 640, and 442) at 0, 6, and 12 mo of aging, resp.
