Name: Ethyltriphenylphosphonium bromideIn 2021 ,《Highly efficient and reversible low-concentration SO2 absorption in flue gas using novel phosphonium-based deep eutectic solvents with different substituents》 was published in Journal of Molecular Liquids. The article was written by Zhao, Yongqi; Dou, Jinxiao; Wei, Aoran; Khoshkrish, Salman; Yu, Jianglong. The article contains the following contents:

Four hydrogen bond acceptors (HBAs) with different carbon chain length substituents, including methyl-triphenyl phosphonium bromide (MTPB), ethyl-tri-Ph phosphonium bromide (ETPB), propyl-triphenyl phosphonium bromide (PTPB), and butyl-tri-Ph phosphonium bromide (BTPB), combined with ethylene glycol (EG) were developed to synthesize four low-viscosity deep eutectic solvents (DESs). In this study, the effect of different substituents in DESs on low-concentration SO2 absorption was systematically studied at 30-70°C. Exptl. results show that the EG-MTPB DES has a higher SO2 absorption capacity and a lower viscosity than other DESs. The reason for the higher SO2 absorption capacity of EG-MTPB DES was described by viscosity experiments and quantum chem. calculations It was shown that the strong polarization ability of the CH3- group promotes the absorption of SO2 by DESs. 1H NMR and FTIR results indicated that chem. interactions primarily exist between the S of SO2 and Br, and the O of SO2 and the H atom of EG form hydrogen bonds. The d. functional theory (DFT) results also confirm that the charge of the Br atom migrated to the S atom. Also, thermostability and regeneration experiments showed that the EG-MTPB DES exhibits good stability and can thus be used for industrial flue gas desulfurization.

In 2022,Yao, Chengbo; Williams, Alana D. N.; Gu, Yiting; Norton, Jack R. published an article in Journal of Organic Chemistry. The title of the article was 《Isomerization of Aziridines to Allyl Amines via Titanium and Chromium Cooperative Catalysis》.Safety of Ethyltriphenylphosphonium bromide The author mentioned the following in the article:

A Ti/Cr cooperative catalyst isomerized aziridines to allyl amines under mild conditions. The reaction tolerated a broad range of aziridines with various nitrogen substituents. The titanium catalyst was most successful in opening 1,2-disubstituted aziridines, forming radical intermediates in a highly regioselective manner. The chromium catalyst appears to abstract an H• from these radical intermediates and then return the H• to the titanium system in the form of an H+ and an electron. The reaction was complementary to previous reports on the isomerization of aziridines to allyl amines.

Naturally occurring benzoxanthenones, which belong to the vast family of lignans, are promising biol. relevant targets. They are biosynthetically produced by the oxidative dimerization of 2-propenyl phenols. In this manuscript, we disclose a powerful automated flow-based strategy for identifying and optimizing a cobalt-catalyzed oxidizing system for the bioinspired dimerization of 2-propenyl phenols. We designed a reconfigurable flow reactor associating online monitoring and process control instrumentation. Our machine was first configured as an automated screening platform to evaluate a matrix of 4 catalysts (plus the blank) and 5 oxidants (plus the blank) at two different temperatures, resulting in an array of 50 reactions. The automated screening was conducted on micromole scale at a rate of one fully characterized reaction every 26 min. After having identified the most promising cobalt-catalyzed oxidizing system, the automated screening platform was straightforwardly reconfigured to an autonomous self-optimizing flow reactor by implementation of an optimization algorithm in the closed-loop system. The optimization campaign allowed the determination of very effective exptl. conditions in a limited number of experiments, which allowed us to prepare the natural products carpanone and polemannone B as well as synthetic analogs.

The article was titled 《Design of Negative and Positive Allosteric Modulators of the Cannabinoid CB2 Receptor Derived from the Natural Product Cannabidiol》.COA of Formula: C20H20BrP The article contains the following contents:

Cannabidiol (CBD), the second most abundant of the active compounds found in the Cannabis sativa plant, is of increasing interest because it is approved for human use and is neither euphorizing nor addictive. Here, we design and synthesize novel compounds taking into account that CBD is both a partial agonist, when it binds to the orthosteric site, and a neg. allosteric modulator, when it binds to the allosteric site of the cannabinoid CB2 receptor. Mol. dynamic simulations and site-directed mutagenesis studies have identified the allosteric site near the receptor entrance. This knowledge has permitted to perform structure-guided design of neg. and pos. allosteric modulators of the CB2 receptor with potential therapeutic utility.

Zhou, Guojun; Ren, Qiqiong; Molokeev, Maxim S.; Zhou, Yayun; Zhang, Jian; Zhang, Xian-Ming published an article in 2021. The article was titled 《Unraveling the Ultrafast Self-assembly and Photoluminescence in Zero-Dimensional Mn2+-Based Halides with Narrow-Band Green Emissions》, and you may find the article in ACS Applied Electronic Materials.Application of 1530-32-1 The information in the text is summarized as follows:

The discovery of narrow-band luminescent materials remains an immense challenge to optimize the performance of white light-emitting diodes (LEDs). So far, the zero-dimensional (0D) Mn2+-based halides with near-unity narrow-band emissions have emerged as a class of promising phosphors in solid-state displays, but the related large-scale synthesis strategies have not been proposed and evaluated. Herein, we report an in situ synthetic process of 0D Mn2+-based halides and utilize (C20H20P)2MnBr4 as a case to investigate the photoluminescence characteristics and the structural essence of ultrafast self-assembly. The bright green emission peak at 523 nm with a full width at half maximum of 48 nm for (C20H20P)2MnBr4 is attributed to the d-d transition (4T1-6A1) of tetrahedrally coordinated [MnBr4]2- centers, and the fabricated white LED device shows a wide color gamut of 103.7% National Television System Committee (NTSC) standard Remarkably, the exptl. and theor. results indicate that there are hydrogen bonding of C-H···Br and weak van der Waals interactions between [C20H20P]+ and [MnBr4]2-, resulting in the root for the realization of ultrafast self-assembly in 0D Mn2+-based halides. This work reveals a feasible and general synthesis method for preparing 0D Mn2+-based halides, thereby providing a possibility for their industrial application in solid-state displays.

The title of the article was 《Cascade Benzannulation Approach for the Syntheses of Lipocarbazoles, Carbazomycins, and Related Alkaloids》.Category: bromides-buliding-blocks The author mentioned the following in the article:

Herein, a state-of-the-art one-pot cascade benzannulation technique for the efficacious synthesis of valuable 3-hydroxy-2-Me carbazoles, a linchpin of more than 25 carbazole-based alkaloids, is unveiled from readily affordable fundamental commodities. The key step of this strategy is gaining aromaticity by site-selective elimination of hydroxyl group controlled by nucleophilicity of the indole ring. The present strategy shows excellent functional group tolerance with a broad substrate scope. The utility of this convenient approach was appealingly exemplified via concise total syntheses of 10 carbazole-based alkaloids possessing significant biol. activities and thus of medicinal importance.

In 2022,Jiang, Ben-Jie; Zhang, Song-Lin published an article in Advanced Synthesis & Catalysis. The title of the article was 《Synthesis of Quinolines and 2-Functionalized Quinolines by Difluorocarbene Incorporation》.Computed Properties of C20H20BrP The author mentioned the following in the article:

A general method was developed to allow de novo construction of quinolines I [R = Me, cyclopropyl, Ph, etc.] and C2-functionalized quinolines II [R1 = Me, cyclopentyl, Ph; R2 = Ph, Bn, 1-naphthyl, etc.; R3 = H, Me] from ortho-alkenyl anilines in the presence of a difluorocarbene precursor. This method exploited a crucial reactivity of in-situ generation of isocyanides from condensation of primary aniline with difluorocarbene. Subsequent α-addition of isocyanide by neighboring alkenyl group constructs the quinoline ring. Furthermore, when a combination of difluorocarbene precursor and Se are present, selenoisocyanate intermediates were tentatively generated that upon nucleophilic addition by ortho-alkenyl produce 2-SeH quinolines. In the presence of a second nucleophile such as anilines, competing nucleophilic addition of anilines to the selenoisocyanate was preferred, generating selenourea intermediate. Further nucleophilic addition of the ortho-alkenyl to selenourea followed by elimination of H2Se produces 2-aminoquinolines. This allows one-step multi-component modular preparation of various C2-functionalized quinolines from readily available starting compounds This method showed good yields, scope and chemoselectivity. It was operationally convenient and friendly without manipulating unpleasant isocyanides. The difluorocarbene-enabled primary amine to isocyanide conversion may be exploited to develop other interesting reactions.
