Ramos Chagas, Gabriela published the artcileSuperhydrophobic and fluorescent properties of fluorinated polypyrene surfaces using various polar linkers prepared via electropolymerization, Application of 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecan-1-amine, the publication is Reactive & Functional Polymers (2019), 65-76, database is CAplus.

Superhydrophobic and fluorescent polypyrene surfaces were synthesized by an electropolymerization process. Six different linkers (ester, thioester, amide, carbamate, thiocarbamate and urea) are used to introduce fluorinated chains (lengths of 4, 6 and 8 carbons) onto pyrene moiety. The electropolymerized surfaces were analyzed by their morphol., surface chem., wettability and fluorescence. The linkers and the length of the fluorinated chain influence on both surface chem. and morphol. confirmed by XPS and SEM anal., resp. Superhydrophobic surfaces were obtained for ester, thioester, carbamate and thiocarbamate series while high hydrophobic surfaces for amide and urea series. Here, we show the possibility to control the surface hydrophobicity, oleophobicity and liquid adhesion with both the linker and the fluorinated chain length. For example, N-H groups seem to induce a decrease in the static contact angle (¦È_w) and in the surface structuration due to their polarity generating smoother surfaces (as for amide and urea series) and yielding to a red-shift in the emission spectra (showed for amide, carbamate, thiocarbamate and urea). The emission of all the polypyrene films is red-shifted compared to the pyrene monomers (excimer emission) and in the green region independently of the side chain. Here, we show that the nature of the heteroatom that connects the pyrene moiety to the fluorinated chain also does great impact on the surface morphol., wetting and fluorescence properties.

One of the major stumbling blocks that has plagued the practical utilization and fundamental studies of the high-T_c superconductors has been the poor interfacial properties exhibited by these systems. In order to control the surface characteristics of high-T_c structures, methods for the spontaneous adsorption of amine reagents into cuprate materials have been developed. These monolayer films allow for control of the wetting properties, corrosion resistance, and adhesion characteristics of these superconductors. The mols. form densely packed, highly oriented structures on the high-T_c surfaces as evidenced by contact angle, XPS, x-ray reflectivity, and corrosion resistance measurements. In this paper, dramatic changes in the interfacial reactivity and adhesion properties of the prototypical high-T_c superconductor, YBa₂Cu₃O₇ , following its modification with linear alkylamines and fluorinated alkylamines reagents are described. Thus, mol. level control over important surface and interfacial properties of cuprate superconductors is demonstrated.

Tardiff, Bennett J. published the artcileRational and Predictable Chemoselective Synthesis of Oligoamines via Buchwald-Hartwig Amination of (Hetero)Aryl Chlorides Employing Mor-DalPhos, Product Details of C30H42NOP, the publication is Journal of Organic Chemistry (2012), 77(2), 1056-1071, database is CAplus and MEDLINE.

A diverse demonstration of synthetically useful chemoselectivity in the synthesis of di-, tri-, and tetraamines (62 examples) by use of Buchwald-Hartwig amination employing a single catalyst system ([Pd(cinnamyl)Cl]₂/L1; L1 = N-(2-(di(1-adamantyl)phosphino)phenyl)morpholine, Mor-DalPhos) was reported. Competition reactions established the following relative preference of this catalyst system for amine coupling partners: linear primary alkylamines and imines > unhindered electron-rich primary anilines, primary hydrazones, N,N-dialkylhydrazines, and cyclic primary alkylamines > unhindered electron-deficient primary anilines, ¦Á-branched acyclic primary alkylamines, hindered electron-rich primary anilines ? cyclic and acyclic secondary dialkylamines, secondary alkyl/aryl and diarylamines, ¦Á,¦Á-branched primary alkylamines, and primary amides. The new isomeric ligand N-[4-[di(1-adamantyl)phosphino]phenyl]morpholine (p-Mor-DalPhos, L2) was prepared in 63% yield and was crystallog. characterized; the [Pd(cinnamyl)Cl]₂/L2 catalyst system exhibited divergent reactivity. Application of the reactivity trends established for [Pd(cinnamyl)Cl]₂/L1 toward the chemoselective synthesis of di-, tri-, and tetraamines was achieved. Preferential arylation was observed at the primary alkylamine position within 2-(4-aminophenyl)ethylamine with [Pd(cinnamyl)Cl]₂/L1 and 4-chlorotoluene (affording I); the alternative regioisomer (II) was obtained when using [Pd(cinnamyl)Cl]₂/L2. These observations are in keeping with coordination chem. studies, whereby binding of 2-(4-aminophenyl)ethylamine to the in situ generated [(L1)Pd(p-tolyl)]⁺ fragment occurred via the primary amine moiety, affording the crystallog. characterized adduct [(L1)Pd(p-tolyl)(NH₂CH₂CH₂(4-C₆H₄NH₂))]⁺OTf^– in 72% yield.

Alsabeh, Pamela G. published the artcileStoichiometric Reactivity Relevant to the Mor-DalPhos/Pd-Catalyzed Cross-Coupling of Ammonia and 1-Bromo-2-(phenylethynyl)benzene, Category: catalysis-chemistry, the publication is Organometallics (2012), 31(3), 1049-1054, database is CAplus.

While Mor-DalPhos/Pd precatalyst mixtures have in general proven to be highly effective for the monoarylation of ammonia employing a range of (hetero)aryl (pseudo)halide cross-coupling partners, we have observed previously that 1-bromo-2-(phenylethynyl)benzene (Ar*Br) is a challenging substrate for this catalyst system. We report herein on our efforts to examine some possible modes of catalyst inhibition by this substrate. Treatment of [CpPd(allyl)] with Mor-DalPhos in the presence of Ar*Br afforded [(¦Ê²-P,N-Mor-DalPhos)Pd(Br)(Ar*)] (1; 85%), which was transformed into [(¦Ê³-P,N,O-Mor-DalPhos)Pd(Ar*)]⁺OTf^– (3; 83%) upon treatment with AgOTf. The characterization of 3 establishes the ability of the Mor-DalPhos ligand to adopt a ¦Ê³-P,N,O structure, which may influence the course of some Pd-catalyzed amination processes. While treatment of 1 with AgOTf in the presence of ammonia, or alternatively treatment of 3 with ammonia, resulted in the clean formation of [(¦Ê²-P,N-Mor-DalPhos)Pd(NH₃)(Ar*)]⁺OTf^– (2), our efforts to isolate this compound were thwarted by the facile loss of ammonia from 2 to give 3. Neither NMR spectroscopic nor x-ray crystallog. data obtained for 1 and 3 support the existence of significant Pd¡¤¡¤¡¤alkyne interactions in these complexes. Treatment of the Pd(0) species [L₂Pd(diphenylacetylene)] (L₂ = Mor-DalPhos, 4; L₂ = CyPFtBu-JosiPhos, 5) with Ar*Br resulted in divergent behavior: while multiple phosphorus-containing products were observed in the case of 4, under analogous conditions 5 was transformed cleanly into [(¦Ê²-P,P-JosiPhos)Pd(Br)(Ar*)] (6). The identification of 6 was facilitated via independent synthesis from Ar*Br, JosiPhos, and [CpPd(allyl)] (90%). These observations suggest that the inferior performance of Mor-DalPhos relative to JosiPhos in the arylation of ammonia using Ar*Br may be attributable in part to the inefficiency with which putative [(Mor-DalPhos)Pd(alkyne)] species re-enter the catalytic cycle via C-Br oxidative addition

The association behavior of the terpolymers of sodium 2-acrylamido-2-methylpropanesulfonate (NaAMPS), N-dodecylmethacrylamide (DodMAm), and N-(2-(perfluorooctyl)ethyl)methacrylamide (PFOEMAm) (A/H(x)/F(y)) and their reference copolymers of NaAMPS and PFOEMAm (A/F(y)) was characterized using ¹⁹F and ¹H NMR, steady state fluorescence, and dynamic light scattering techniques in water (or D₂O) containing 0.1 M NaCl. The terpolymers formed micelle-like aggregates where hydrophobic microdomains are formed by hydrophobic associations among the perfluorooctylethyl (PFOE) and dodecyl (Dod) groups, the PFOE group exhibiting a stronger tendency for interpolymer association than the Dod groups. A careful anal. of the characterization data led to a conclusion that the hydrophobic microdomain formed from the terpolymer is microscopically phase separated into the fluorocarbon phase and hydrocarbon phase.

The parallel synthesis of O-aryloxyamines remains an unfulfilled need in the field of medicinal chem. and fragment-based approaches. To fill this gap a solution-phase two-step process based on (1) a copper-catalyzed cross-coupling of aryl boronic acids with a fluorous tagged N-hydroxyphthalimide, and (2) a supported aminolysis was designed and optimized using Taguchi’s method. A library of O-aryloxyamines was synthesized in high yields with high purity and diversity.
