Wu, Xiang; Ding, Du; Zhang, Ying; Jiang, Hua-Jie; Wang, Tao; Zhao, Li-Ping published their research in Chemical Communications (Cambridge, United Kingdom) in 2021. The article was titled 《Enantioselective synthesis of 1-aminoindene derivatives via asymmetric Bronsted acid catalysis》.Computed Properties of C20H20BrP The article contains the following contents:

A catalytic asym. iminium ion cyclization reaction of simple 2-alkenylbenzaldimines using a BINOL-derived chiral N-triflyl phosphoramide was described. The corresponding 1-aminoindenes I [R1 = H, Ph, Bn, etc.; R2 = H, Me, Ph, etc.; R3 = H, 5-F, 5-Me, etc.] and tetracyclic 1-aminoindanes II [R4 = H, Me, Et, etc.] were formed in good yields and high enantioselectivities. Further, the chem. utility of the obtained enantiopure 1-aminoindene was demonstrated for the asym. synthesis of (S)-rasagiline. The experimental process involved the reaction of Ethyltriphenylphosphonium bromide(cas: 1530-32-1Computed Properties of C20H20BrP)

Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.Computed Properties of C20H20BrP

Reference of Ethyltriphenylphosphonium bromideIn 2021 ,《Electrochemical oxidative Z-selective C(sp2)-H chlorination of acrylamides》 appeared in Chemical Communications (Cambridge, United Kingdom). The author of the article were Harnedy, James; Hareram, Mishra Deepak; Tizzard, Graham J.; Coles, Simon J.; Morrill, Louis C.. The article conveys some information:

An electrochem. method for the oxidative Z-selective C(sp2)-H chlorination of acrylamides was developed. This catalyst and organic oxidant free method was applicable across various substituted tertiary acrylamides and provides access to a broad range of synthetically useful Z-β-chloroacrylamides in good yields (22 examples, 73% average yield). The orthogonal derivatization of the products was demonstrated through chemoselective transformations and the electrochem. process was performed on gram scale in flow. After reading the article, we found that the author used Ethyltriphenylphosphonium bromide(cas: 1530-32-1Reference of Ethyltriphenylphosphonium bromide)

In 2019,Chemical Communications (Cambridge, United Kingdom) included an article by Murai, Masahito; Nishimura, Kengo; Takai, Kazuhiko. HPLC of Formula: 1530-32-1. The article was titled 《Palladium-catalyzed double-bond migration of unsaturated hydrocarbons accelerated by tantalum chloride》. The information in the text is summarized as follows:

The operationally simple palladium-catalyzed double-bond migration without heteroatom-containing coordinating functional groups was described. Addition of TaCl5 as a second catalyst greatly enhanced the migration efficiency to provided β-alkylstyrenes through migration of up to a five-carbon chain. Both catalysts were com. available and the reaction occurred without external ligands under neutral conditions. The reaction proceeded via generation of π-allyl palladium species, which enabled the chemoselective double-bond migration of hydrocarbons in the presence of allyl ethers. Remote functionalization through double-bond migration was also demonstrated using FeCl3 as a second catalyst. In the experiment, the researchers used Ethyltriphenylphosphonium bromide(cas: 1530-32-1HPLC of Formula: 1530-32-1)

In 2022,Henriques, Dina Schwarz G.; Rojo-Wiechel, Elena; Klare, Sven; Mika, Regine; Hothker, Sebastian; Schacht, Jonathan H.; Schmickler, Niklas; Gansauer, Andreas published an article in Angewandte Chemie, International Edition. The title of the article was 《Titanocene(III)-Catalyzed Precision Deuteration of Epoxides》.Application In Synthesis of Ethyltriphenylphosphonium bromide The author mentioned the following in the article:

Authors describe a titanocene(III)-catalyzed deuterosilylation of epoxides that provides β-deuterated anti-Markovnikov alcs. with excellent D-incorporation, in high yield, and often excellent diastereoselectivity after desilylation. The key to the success of the reaction is a novel activation method of Cp2TiCl2 and (tBuC5H4)2TiCl2 with BnMgBr and PhSiD3 to provide [(RC5H4)2Ti(III)D] without isotope scrambling. It was developed after discovering an off-cycle scrambling with the previously described method. Precision deuteration can be applied to the synthesis of drug precursors and highlights the power of combining radical chem. with organometallic catalysis. In the experiment, the researchers used many compounds, for example, Ethyltriphenylphosphonium bromide(cas: 1530-32-1Application In Synthesis of Ethyltriphenylphosphonium bromide)

Application In Synthesis of Ethyltriphenylphosphonium bromideIn 2022 ,《Regio-regular and cross-conjugated poly(thienylene vinylene)s through acyclic diene metathesis》 appeared in Journal of Polymer Science (Hoboken, NJ, United States). The author of the article were Bader, Yousef M. Katba; Guan, Chao; Qin, Yang. The article conveys some information:

Poly(thienylene vinylene)s (PTV’s) are early examples of conjugated polymers but have not been extensively studied when compared with closely analogous polythiophenes. PTV’s synthesized through previously reported techniques are similar in structures that contain various alkyl or alkoxy side-chains that exert limited impact on the polymer electronic properties. Herein, we report the preparation of a series of regio-regular PTV’s (rr-PTV’s) bearing cross-conjugated side-chains through ADMET polymerization of a common brominated di(thienylene vinylene) (DTV) monomer followed by PPM reactions on the resulting brominated PTV. These new polymers contain a bulky silyloxy alkyl side-chain and a functionalized thiophene moiety on every main-chain thiophene unit, and their regio-regular placement is confirmed by NMR spectroscopy. The thienyl based side-groups broaden polymer absorption ranges and at the same time lead to uncommon emission properties that are results of light-induced charge transfer events between the polymer main-chains and side-chains. Removal of the silyl groups on one of these rr-PTV’s led to insoluble materials and x-ray diffraction experiments on the collected solids displayed distinct scattering peaks that are absent from similarly functionalized regio-random PTV’s reported previously, thus suggesting better crystallinity originated from regio-regularity.
