This paper presents the first general examples of selective palladium-catalyzed mono-¦Á-arylation of aryl and heteroaryl ketones with aryl phosphates. The catalyst system, consisting of [Pd(2-butenyl)Cl]₂ and MorDalPhos, exhibited high catalytic reactivity toward this reaction. A wide range of aryl phosphates were efficiently coupled with aryl and heteroaryl ketones with good selectivity. Excellent-to-good product yields were afforded. The gram-scale reaction was conducted smoothly. Reductive elimination or transmetalation might be a rate-determining step in this reaction.

Xiao, Ke published the artcileSimultaneous achievement of refractory pollutant removal and energy production in saline wastewater treatment, Safety of 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecan-1-amine, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2019), 845-853, database is CAplus.

A novel solar-wastewater-energy recovery system was presented to simultaneously remove refractory organic pollutants from saline wastewater and produce energy. To accomplish this goal, a two-chamber cell was fabricated. The anode chamber integrating photo-oxidation and flocculation was developed by using a TiO₂ nanotube array (TNA) and Al foil. A dopamine modified carbon felt (DPA/CF) electrode was located in the cathode chamber to produce H₂O₂ by the two-electron reduction of O₂ with electrons generated on the anodes. Under sunlight irradiation, the TNA photoanode initiated the degradation of perfluorodecylamine (PFDA) as typical refractory pollutant and selectively transformed its organic nitrogen to N₂ and NO₃^– with yields of 87% and 12%, resp. Compared with PFDA removal efficiency using single flocculation, the efficiency was improved by more than 5 times (ca. 96.6%) in the combined process of photo-oxidation and flocculation. H₂O₂ production was also achieved using the DPA/CF cathode, obtaining a high concentration of 5.0 mM. Furthermore, this study revealed that the reversible reaction between dehydrogenation and hydrogenation on polydopamine accomplished the catalytic reduction of O₂ to H₂O₂. The present study proposes a new approach involving energy recovery in saline wastewater treatment for an energy-sustainable society.

Chen, Zicong published the artcilePalladium-Catalyzed C(sp²)-N Bond Cross-Coupling with Triaryl Phosphates, Safety of 4-(2-(Di(adamantan-1-yl)phosphino)phenyl)morpholine, the publication is Journal of Organic Chemistry (2019), 84(10), 6366-6376, database is CAplus and MEDLINE.

The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(¦Ð-cinnamyl)Cl]₂ enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this reaction condition. The solvent-free amination reactions are also successful in both solid coupling partners. The gram-scale cross-coupling is achieved by this catalytic system.

Valles-Miret, Mariona published the artcileA generic small-molecule microarray immobilization strategy, Recommanded Product: 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecan-1-amine, the publication is Tetrahedron Letters (2011), 52(50), 6819-6822, database is CAplus.

Small-mol. microarrays are often limited by the requirement for each compound undergoing immobilization to contain a common functional group or by the need to prepare glass slides containing photo-reactive groups. Herein, the authors present a generic strategy that allows any compound library to be immobilized. This was achieved by printing a fluorous-tagged photo-reactive 3-aryl-3-trifluoromethyldiazirine, which undergoes nonselective insertion into compounds following UV-activation, onto fluorous-functionalized glass slides. The arrays could be reused following aqueous stripping and re-assessment of the compounds with the same protein or another target of interest.

Godeau, Guilhem published the artcileOne-pot Staudinger Ureation reaction to develop superhydrophobic/oleophobic surfaces with urea linkers, SDS of cas: 30670-30-5, the publication is Materials & Design (2017), 116-122, database is CAplus.

In this work, we report for the first time the use of the one-pot Staudinger ureation to link an azido monomer to a perfluorinated amine by taking advantage of a variation of the Staudinger reaction using CO₂ as an electrophile to form an isocyanate in-situ. The formed isocyanate directly reacts with various perfluorinated amines to form the corresponding urea. This chem. pathway is successfully used to prepare new perfluorinated monomers. The monomers were then electrodeposited to form structured surfaces with different wetting properties. Various properties were obtained such as: parahydrophobicity, super hydrophobicity, oleophilicity and strong oleophobicity. This study shows the important influence of the perfluorinated chain on both polymerization and surface properties. This work also illustrates the efficiency of the one-pot Staudinger ureation for new urea monomer elaboration.

An efficient and versatile ‘green’ catalytic system for the Buchwald-Hartwig cross-coupling reaction in water is reported. In an aqueous micellar medium, the combination of t-BuXPhos with [(cinnamyl)PdCl]₂ showed excellent performance for coupling of aryl bromides or chlorides with a large set of amines, amides, ureas, and carbamates. The method is functional-group tolerant, proceeds smoothly (30 to 50 °C), and provides rapid access to the target compounds in good to excellent isolated yields. When applied to the synthesis of a known NaV1.8 modulator, this method led to a significant improvement of the E-factor in comparison with classical organic synthesis.

Nivet, J. B. published the artcileSynthesis and bioacceptability of fluorinated surfactants derived from F-alkylated tertiary amines, COA of Formula: C10H6F17N, the publication is European Journal of Medicinal Chemistry (1992), 27(9), 891-8, database is CAplus.

Two methods for synthesizing tertiary F-alkylated amines are reported. The more general method allows the access in 56-87% yields to various N,N-dialkyl F-alkyl amines. These amines are key intermediates leading in 52-96% yields to several families of surfactants, including zwitterionic and cationic derivatives and amine oxides, potentially useful in the formulation of fluorocarbon emulsions for diagnostic and therapeutic uses. The toxicity of the new surfactants and the influence of the polar head were assessed: the long chain compounds C₈F₁₇(CH₂)₃N⁺Me₂(CH₂)_mCO₂^– (8; m = 3, 4, 5); C₈F₁₇(CH₂)₃N⁺R₃ X^– (9; R = Me, X = Cl; R = Et, X = Br) and C₈F₁₇(CH₂)₃NMe₂O were found to be toxic for cell cultures and the zwitterionic compounds, e.g., 8, have a LD₅₀ <250 mg·kg bw^-1 in mice. The hemolysis test highlights the influence of the polar head: the zwitterionic compounds were found to be non-hemolytic even at remarkably high concentrations (100 g L^-1 for 8), whereas the cationic compounds 9 are highly hemolytic even at very low concentrations (0.05 g L^-1).

The compounds Pd(η³-1-Ph-C₃H₄)(η⁵-C₅H₅) (I), Pd₂(dba)₃ (II), Pd(OAc)₂ (III), and [Pd(η³-1-Ph-C₃H₄)Cl]₂ (IV) are frequently used as catalyst precursors for a variety of cross-coupling processes, including Suzuki-Miyaura, Heck-Mizoroki, Sonogashira, and Buchwald-Hartwig reactions.

Inter alia that steric requirements prevent Xphos and Mor-Dalphos from forming 2:1 Pd(0) complexes and, surprisingly, that 1:1 Pd(0) complexes of Xphos and Mor-Dalphos are unstable with respect to dissociation to free ligand and Pd metal were found. These two ligands and, by implication, other sterically demanding phosphine ligands do not form Pd(0) compounds
