On June 30, 2011, Hatano, Akihiko; Okada, Munehiro; Shimazaki, Kei; Uehara, Sanae; Ishikawa, Yuta; Matsumoto, Arata; Fujita, Yudai; Nishimura, Makoto published an article.COA of Formula: C13H11BrS The title of the article was Inhibitory effects on microbial growth using the derivatives of benzyl phenyl sulfide. And the article contained the following:

We investigated the antimicrobial activities of twelve derivatives of benzyl Ph sulfide by using Min. Inhibitory Concentration (MIC) and Min. Bactericidal Concentration (MBC) values against 10 microbial strains. These derivatives of benzyl Ph sulfides were synthesized by means of the nucleophilic coupling reaction at our laboratory MIC testing revealed that all synthetic derivatives of benzyl and 4-methoxybenzyl Ph sulfides had no effect against the tested microbial strains. However, the compounds of 4-nitrobenzyl Ph sulfide showed antimicrobial activity against many of the tested strains. Above all, 4-nitrobenzyl 4-chlorophenyl sulfide 11 exhibited the strongest and widest ranging inhibitory effects among the twelve synthetic compounds We researched the antimicrobial activities of the coupling materials of sulfide. As a result, it was considered important for the expression of antimicrobial activities that the sulfide had a 4-nitrobenzyl group and 4-chlorophenyl group in the same mol. as in the case of benzyl Ph sulfide. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).COA of Formula: C13H11BrS

On July 16, 2021, Kolb, Simon; Ahlburg, Nils L.; Werz, Daniel B. published an article.Formula: C8H10O2 The title of the article was Friedel-Crafts-Type Reactions with Electrochemically Generated Electrophiles from Donor-Acceptor Cyclopropanes and -Butanes. And the article contained the following:

A general electrochem. method to functionalize donor-acceptor (D-A) cyclopropanes and -butanes with arenes utilizing Friedel-Crafts-type reactivity is discussed. The catalyst-free strategy relies on the direct anodic oxidation of the strained carbocycles, which leads after C(sp3)-C(sp3) cleavage to radical cations that act as electrophiles for the arylation reaction. Broad reaction scopes in regard to cyclopropanes, cyclobutanes, and aromatic reaction partners are presented. Addnl., a plausible electrolysis mechanism is proposed. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

On December 31, 2020, Li, Yuqiang; Luo, Yixin; Peng, Long; Li, Yangyang; Zhao, Binzhi; Wang, Wang; Pang, Hailiang; Deng, Yi; Bai, Ruopeng; Lan, Yu; Yin, Guoyin published an article.Related Products of 321-28-8 The title of the article was Reaction scope and mechanistic insights of nickel-catalyzed migratory Suzuki-Miyaura cross-coupling. And the article contained the following:

In this work, a Ni-catalyzed migratory Suzuki-Miyaura cross-coupling featuring high benzylic or allylic selectivity has been developed. With this method, unactivated alkyl electrophiles and aryl or vinyl boronic acids can be efficiently transferred to diarylalkane or allylbenzene derivatives under mild conditions. Importantly, unactivated alkyl chlorides can also be successfully used as the coupling partners. To demonstrate the applicability of this method, showcase that this strategy can serve as a platform for the synthesis of terminal, partially deuterium-labeled mols. from readily accessible starting materials. Exptl. studies suggest that migratory cross-coupling products are generated from Ni(0/II) catalytic cycle. Theor. calculations indicate that the chain-walking occurs at a neutral nickel complex rather than a cationic one. In addition, the original-site cross-coupling products can be obtained by alternating the ligand, wherein the formation of the products has been rationalized by a radical chain process. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Related Products of 321-28-8

Vora, Harit U.; Silvestri, Anthony P.; Engelin, Casper J.; Yu, Jin-Quan published an article in 2014, the title of the article was Rhodium(II)-Catalyzed Nondirected Oxidative Alkenylation of Arenes: Arene Loading at One Equivalent.Reference of 1-Fluoro-2-methoxybenzene And the article contains the following content:

A bimetallic RhII catalyst promoted the C-H alkenylation of simple arenes at 1.0 equiv without the use of a directing group. A phosphine ligand as well as cooperative reoxidation of RhII with Cu(TFA)2 and V2O5 proved essential in providing monoalkenylated products in good yields and selectivities, especially with di- and trisubstituted arenes. E.g., in presence of [Rh2(OAc)4], tricyclohexylphosphine, Cu(TFA)2, and V2O5 in DCE under N2 at 140 °C, alkenylation of PhMe with Bu acrylate gave a 74% mixture (1:1) of (E)-I and (E)-II.

On March 31, 2021, Wu, Zhuo; Wei, Feng; Wan, Bin; Zhang, Yanghui published an article.Application In Synthesis of 2-Methoxynaphthalene The title of the article was Pd-Catalyzed ipso,meta-Dimethylation of ortho-Substituted Iodoarenes via a Base-Controlled C-H Activation Cascade with Dimethyl Carbonate as the Methyl Source. And the article contained the following:

A Me group can have a profound impact on the pharmacol. properties of organic mols. Hence, developing methylation methods and methylating reagents is essential in medicinal chem. We report a palladium-catalyzed dimethylation reaction of ortho-substituted iodoarenes using di-Me carbonate as a Me source. In the presence of K2CO3 as a base, iodoarenes are dimethylated at the ipso- and meta-positions of the iodo group, which represents a novel strategy for meta-C-H methylation. With KOAc as the base, subsequent oxidative C(sp3)-H/C(sp3)-H coupling occurs; in this case, the overall transformation achieves triple C-H activation to form three new C-C bonds. These reactions allow expedient access to 2,6-dimethylated phenols, 2,3-dihydrobenzofurans, and indanes, which are ubiquitous structural motifs and essential synthetic intermediates of biol. and pharmacol. active compounds The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Application In Synthesis of 2-Methoxynaphthalene

On March 8, 2016, Sugihara, Shinji; Kawamoto, Yuki; Maeda, Yasushi published an article.Reference of 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was Direct Radical Polymerization of Vinyl Ethers: Reversible Addition-Fragmentation Chain Transfer Polymerization of Hydroxy-Functional Vinyl Ethers. And the article contained the following:

Unprecedented controlled radical vinyl polymerization (CRP) of vinyl ethers using reversible addition-fragmentation chain transfer (RAFT) polymerization is reported. In order to overcome the challenge of direct radical polymerization of vinyl ethers, com. hydroxy-functional vinyl ethers such as 2-hydroxyethyl vinyl ether (HEVE) were subjected to free radical polymerization, generating vinyl polymers without polyacetals obtained by self-polyaddition polymerization In the case of bulk polymerization using a nonacidic azo-initiator such as di-Me 2,2′-azobis(2-methylpropionate), conventional free radical vinyl polymerization occurred with sufficiently high number-average mol. weight For example, poly(HEVE) was produced from the corresponding HEVE monomer with Mn = 26 400 in high yield, ≥75%. The resulting polymer was nearly identical to the polymer prepared by living cationic polymerization using the protected monomers except for the steric regularity (meso dyads are 51% and 67% for radical and cationic polymerizations, resp.). Furthermore, cyanomethyl methyl(phenyl)carbamodithioate was found to be an efficient RAFT agent, enabling the CRP of hydroxy-functional vinyl ethers. Under the polymerization conditions, poly(HEVE) macromol. chain transfer agent (macro-CTA) was prepared The kinetic studies of RAFT polymerization showed a linear increase of the mol. weight, with up to 50% monomer conversion and relatively low polydispersities (Mw/Mn < 1.38). In addition, chain extension experiments including block copolymerization with vinyl acetate and N-vinylpyrrolidone were demonstrated using the resulting poly(HEVE) macro-CTA to confirm the "livingness" of the poly(HEVE).
