Benzyl alcs. I [X = OMe, H, CO₂Na, CO₂Me, CO₂H] are oxidized cleanly and efficiently to the corresponding aldehydes II under irradiation using flavin photocatalysts, e.g., III [R¹ = R² = (CH₂)₂(CF₂)₇CF₃; R¹ = CH₂CH₂OMe, R² = Me, (CH₂)₂(CF₂)₇CF₃] and IV [R³ = H, Me, R⁴ = Ac; R³ = Me, R⁴ = C(:O)(CH₂)₁₄Me] and aerial oxygen as the terminal oxidant in homogeneous aqueous solution Turnover frequencies (TOF) of more than 800 h^-1 and turnover numbers (TON) of up to 68 were obtained. Several flavin photocatalysts with fluorinated or hydrophobic aliphatic chains were immobilized on solid supports like fluorous silica gel, reversed phase silica gel or entrapped in polyethylene pellets. The catalytic efficiency of the heterogeneous photocatalysts was studied for the oxidation of different benzyl alcs. in water and compared to the analogous homogeneous reactions. Removal of the heterogeneous photocatalyst stops the reaction conversion immediately, which shows that the immobilized flavin is the catalytically active species. The immobilized catalysts are stable, retain their reactivity if compared to the corresponding homogeneous systems and are easily removed from the reaction mixture and reused. TOF of up to 26 h^-1, TON of 280 and up to 3 reaction cycles without loss of activity are possible with the heterogeneous flavin photocatalysts.

Sawatzky, Ryan S. published the artcileA Comparative Ancillary Ligand Survey in Palladium-Catalyzed C-O Cross-Coupling of Primary and Secondary Aliphatic Alcohols, HPLC of Formula: 1237588-12-3, the publication is European Journal of Organic Chemistry (2016), 2016(14), 2444-2449, database is CAplus.

The utility of RockPhos, Ad-BippyPhos, JosiPhos (CyPF-tBu), and Mor-DalPhos in palladium-catalyzed C-O cross-coupling reactions involving aliphatic alcs. and (hetero)aryl halides under analogous conditions was examined, both at room temperature and at elevated temperature (90 ¡ãC). In general, the RockPhos-based catalyst system proved superior, especially at room temperature, but catalysts based on the other ligands examined also proved effective across a range of C-O cross-couplings, in some cases providing better catalytic performance than RockPhos. New reactivity was established in terms of the scope of room temperature reactions. Proof-of-principle examples of such cross-couplings involving aryl mesylates were also demonstrated.

The synthesis of different types of amphiphilic compounds containing peptidoamine groups leads to surfactants with original properties such as the ability to coordinate metal ions. Water soluble acylcarcinine and alkylamidocarnosine surfactants are compared and the preparation of a silyloxyalkylamidocarnosine is described. The latter can be copolymerized with tetraalkoxysilanes to yield amphipathic organo-mineral solids that are also good ligands for metal cations.

Sasso, Barbara published the artcileSynthesis of ¦Ø-End Group Functionalized Poly(methyl methacrylate)s via RAFT Polymerization, Product Details of C10H6F17N, the publication is Macromolecules (Washington, DC, United States) (2010), 43(18), 7453-7464, database is CAplus.

“Living” poly(Me methacrylate) (PMMA), prepared by the RAFT technique, reacted with maleic anhydride to give succinic anhydride-terminated PMMA (SA-PMMA) in very high yield. The ¦Ø-terminal anhydride residues react in high yields with primary alcs., primary amines and aromatic amines. As examples, SA-PMMA reacted with 1H,1H,2H,2H-perfluorodecylamine to give a polymer containing 5.78% of fluorine; with Disperse Orange 3 to give a dye-labeled PMMA; with 9-hydroxymethylanthracene to give a fluorescently labeled PMMA; with norephedrine to give a polymer with a biol. active end group; and with 4,4′-diaminophenymethane to give amine-ended PMMA. The latter reacted smoothly with fluorescein isocyanate to give a fluorescently labeled PMMA. In these examples the fraction of polymer chains functionalized were in the range 75-95%. Allowing for the fact the starting PMMAs were up to 96% “living”, these loadings correspond to functionalization yields, for the anhydride addition plus the reaction with the nucleophiles, of 81-99%.

Petkevich, S. K. published the artcileSynthesis of Fluorine-Containing Derivatives of 5-Arylisoxazoles and 4,5-Dichlorothiazole, Related Products of catalysis-chemistry, the publication is Russian Journal of General Chemistry (2018), 88(2), 234-240, database is CAplus.

Alkylation of fluorophenols and phenolic aldehydes with 5-phenyl(p-tolyl)-3-chloromethylisoxazole under the Williamson reaction conditions afforded the corresponding ethers. Condensation of the resulting phenolic aldehyde derivatives and 5-phenyl(p-tolyl)isoxazole-3-carbaldehydes with p-fluoroaniline resulted in fluorine-containing azomethines. Acylation of fluorinated amines with 5-(p-tolyl)isoxazole- and 4,5- dichloroisothiazole-3-carbonyl chlorides gave rise to fluorinated amides bearing isoxazole and isothiazole fragments, representatives of which showed a synergistic effect in compositions with insecticides.

MacLean, Mark A. published the artcileDiversification of edaravone via palladium-catalyzed hydrazine cross-coupling: Applications against protein misfolding and oligomerization of beta-amyloid, Related Products of catalysis-chemistry, the publication is Bioorganic & Medicinal Chemistry Letters (2016), 26(1), 100-104, database is CAplus and MEDLINE.

N-Aryl derivatives of edaravone were identified as potentially effective small mol. inhibitors of tau and beta-amyloid aggregation in the context of developing disease-modifying therapeutics for Alzheimer’s disease (AD). Palladium-catalyzed hydrazine monoarylation protocols were then employed as an expedient means of preparing a focused library of 21 edaravone derivatives featuring varied N-aryl substitution, thereby enabling structure-activity relationship (SAR) studies. On the basis of data obtained from two functional biochem. assays examining the effect of edaravone derivatives on both fibril and oligomer formation, it was determined that derivatives featuring an N-biaryl motif were four-fold more potent than edaravone.

De Bruycker, Kevin published the artcileCovalent Fluorination Strategies for the Surface Modification of Polydienes, Synthetic Route of 30670-30-5, the publication is Macromolecular Rapid Communications (2017), 38(11), n/a, database is CAplus and MEDLINE.

Nonreactive additives are widely applied to enhance polymer properties but can leach out of the material over time. In this work, two essentially different fluorinated additives bearing a triazolinedione moiety are synthesized and grafted on several polydiene backbones (acrylonitrile-butadiene-styrene, styrene-butadiene, and styrene-isoprene-styrene (SIS) copolymers), either by dip-coating or by reaction in solution The resulting polymers are analyzed by contact angle goniometry, size exclusion chromatog., and NMR, IR, and XPS. Independent of the modification procedure, the fluorophilic perfluoroalkyl additive is found at the material surface, thereby yielding a more hydrophobic surface. For SIS thermoplastic elastomers, for example, contact angles up to 125¡ã can be obtained.

Guittard, Frederic published the artcileSynthesis and behavior at the air-water interface of fluorinated nonionic surfactants containing two methylated polyoxyethylene moieties, Related Products of catalysis-chemistry, the publication is Journal of Colloid and Interface Science (1996), 177(1), 101-05, database is CAplus and MEDLINE.

The nonionic surfactants of the type polyoxyethylated, monomethylated, and containing a fluorinated tail were synthesized from 2-(F-alkyl)ethylamines. These compounds have two polyethoxylated tails with a perfectly defined number of oxyethylene motifs. Compared with their bipodal homologs within the F-alkylated series, these new structures were easily obtained from com. raw materials which are the 2-(F-alkyl)ethyliodides. The evaluation of their behavior at the air-water interface has been studied from measurements of surface tension vs. variation of concentration This clearly shows the variation of the critical micelle concentration (c.m.c.) from 1.0.10^-5 to 2.5.10^-3 mol.liter^-1 and of the surface area per surfactant mol. vs. studied structure. The N,N-dipolyethoxylene methoxyether of 2-(F-alkyl)ethylamines so realized exhibit noteworthy properties as nonionic fluorinated surfactants.

Chemoselective palladium-phosphine-catalyzed borylation of halogenated aryl triflates TfOC₆H_nY_4-nX (X = Cl, Br; Y = H, OMe, F, Me, PhCH₂, aryl, CN) gave boryl triflates TfOC₆H_nY_4-nBpin, which can be applied for Suzuki coupling with aryl chlorides in one-pot two-step procedure, giving functionalized biaryls. This study reports the palladium-catalyzed chemoselective borylation of (poly)halogenated aryl triflates with a reactivity order of C-Cl>C-OTf. A catalyst system comprising Pd(OAc)₂ and SelectPhos (L1) enables a reaction with high reactivity and chemoselectivity. The consecutively chemoselective borylation reaction followed by the chemoselective intermol. Suzuki-Miyaura reaction can be performed using a one-pot two-step approach to synthesize unsym. biaryl compounds containing the triflate moiety. The reaction can be scaled up to the gram scale without diminishing the yield and chemoselectivity.
