Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about One-pot solvent-free synthesis of quinolines by C-H activation/C-C Bond formation catalyzed by recyclable iron(III) triflate.

A novel application of highly stable Fe(OTf)3 as an efficient catalyst for a carbon-carbon bond formation by the activation of a terminal alkyne carbon-hydrogen (C-H) bond under solvent-free reaction conditions is described. Notably, this protocol of green synthesis (green chem.), which produced quinolines by a reaction of amines, aldehydes and terminal aryl alkynes, shows attractive characteristics including concise one-pot reaction conditions, high atom economy, very limited energy consumption and the sequential catalytic process requires only a catalytic (5 mol%) amount of Fe(OTf)3 and short reaction time. Meanwhile, the catalyst was easily recovered from the reaction system and reused smoothly with only a little loss of activity. The synthesis of the target compounds was achieved using (aryl)alkynes, aryl aldehydes and aryl amines as starting materials. The title compounds thus formed included 2,4-diphenylquinoline, 2-(2,4-dichlorophenyl)-6-methyl-4-phenylquinoline (I), the crystal structure of which was determined, and 6-methyl-4-phenyl-2-(2-thienyl)quinoline, etc.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Angewandte Chemie, International Edition called Chirality-Dependent Second-Order Nonlinear Optical Effect in 1D Organic-Inorganic Hybrid Perovskite Bulk Single Crystal, Author is Fu, Dongying; Xin, Jianli; He, Yueyue; Wu, Shichao; Zhang, Xinyuan; Zhang, Xian-Ming; Luo, Junhua, which mentions a compound: 334618-07-4, SMILESS is Cl.Cl.N[C@H]1CCCNC1, Molecular C5H14Cl2N2, Name: (S)-Piperidin-3-amine dihydrochloride.

The introduction of chirality into organic-inorganic hybrid perovskites (OIHPs) is expected to achieve excellent photoelec. and nonlinear materials related to CD. Owing to the existence of asym. center and intrinsic chirality in the chiral OIHPs, the different efficiencies of second harmonic generation (SHG) signal occurs when the circularly polarized light (CPL) with different phases passes through the chiral crystal, which is defined as second harmonic generation CD (SHG-CD). Here, the SHG-CD effect is developed in bulk single crystals of chiral one-dimensional (1D) [(R/S)-3-aminopiperidine]PbI4. It is the first time that CPL is distinguished using chirality-dependent SHG-CD effect in OIHPs bulk single crystals. Such SHG-CD technol. extends the detection range to near IR region (NIR). In this way, the anisotropy factor (gSHG-CD) through SHG-CD signal is as high as 0.21.

Related Products of 63295-48-7. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Solution processed intrinsically conductive polymer films with high thermoelectric properties and good air stability. Author is Yao, Hongyan; Fan, Zeng; Li, Pengcheng; Li, Bichen; Guan, Xin; Du, Donghe; Ouyang, Jianyong.

It is important to study thermoelec. (TE) materials because they can directly convert heat into electricity. Although intrinsically conducting polymers have the advantages of nontoxicity, low cost, high mech. flexibility and low thermal conductivity, their thermoelec. properties must be significantly improved for practical application. Here, we report a solution-processed conducting polymer, poly(3,4-ethylenedioxythiophene):trifluoromethanesulfonate (PEDOT:OTf), with very high TE properties. As-prepared PEDOT:OTf films from their precursor solution can exhibit a power factor of 346 ± 39 μW m-1 K-2. The power factor can be further enhanced by a post treatment with NaOH or a reducing agent like glucose or ascorbic acid. The NaOH treatment can give rise to a power factor of 568 ± 64 μW m-1 K-2 with a Seebeck coefficient of 49.2 ± 1.4 μV K-1 and an elec. conductivity of 2342 ± 98 S cm-1. This power factor is higher than those obtained by treatment with the reducing agents. The different power factors by NaOH and reducing agent treatments are attributed to their different effects on the doping. The NaOH treatment can remove the protonic doping while the reducing agents can lower the normal oxidation level of PEDOT. The charge carriers due to protonic acid doping have lower energy, and thus the removal of protonic acid doping can significantly enhance the Seebeck coefficient while not lowering the elec. conductivity too much.

Six trinuclear monosubstituted complexes of the type Ru3(CO)11L were synthesized by the reaction of Ru3(CO)12 with phosphine ligands [L = Ph2P(C6H4Me-p), Ph2PC6F5, P(3,5-CF3C6H3)3, P(C6H4Cl-p)3, P(C6H4Me-p)3, PhP(C6H4OCH3-p)2] using the radical anion catalyzed method. The structures of the resulting clusters were elucidated by elemental analyses and spectroscopic methods, including IR, 1H NMR, 13C NMR and 31P NMR spectroscopy. 31P NMR spectra of the complexes Ru3(CO)11P(C6H4Me-p)3 and Ru3(CO)11P(C6H4Cl-p)3 showed splitting of the phosphorus signals into triplets. X-ray crystallog. studies of five complexes were carried out. Out of the three unidentate tertiary phosphine complexes, Ru3(CO)11P(C6H4Me-p)3 and Ru3(CO)11P(C6H4Cl-p)3 are ordered while the complex Ru3(CO)11P(3,5-CF3-C6H3)3 exhibits disorder with respect to the trifluoromethyl groups. In all the five monosubstituted complexes, the ligand occupies the equatorial position due to steric reasons and coordination of the ligands are only at the phosphorus atom. The effect of substitution resulted in significant differences in the Ru-Ru distances. Out of the three Ru-Ru bonds, the one which is cis to the ligand is noticeably longer and the mean value for this longest Ru-Ru bond is 2.889 Å, while the mean value for the two shorter Ru-Ru bonds is 2.841 Å. The P-C distances are in the range 2.333(6)-2.354(6) Å. The equatorial Ru-CO moieties are almost linear and the average value for all the five complexes studied range from 176.3 to 177.6°, while the axial CO groups are slightly bent, ranging from 173.8 to 174.1°.

Product Details of 144222-22-0. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Boc-4-(Aminomethyl)piperidine, is researched, Molecular C11H22N2O2, CAS is 144222-22-0, about Rh(III)-catalyzed three-component syn-carboamination of alkenes using arylboronic acids and dioxazolones. Author is Lee, Sumin; Rovis, Tomislav.

Herein we report a Rh(III)-catalyzed three-component carboamination of alkenes from readily available aryl boronic acids as a carbon source and dioxazolones as nitrogen electrophiles. This protocol provides facile access to valuable amine products including α-amino acid derivatives in good yield and excellent regioselectivity without the need for a directing functionality. A series of experiments suggest a mechanism in which the Rh(III) catalyst undergoes transmetalation with the aryl boronic acid followed by turnover limiting, alkene migratory insertion into the Rh(III)-aryl bond. Subsequently, fast Rh-nitrene formation provides the syn-carboamination product selectively after reductive elimination and proto-demetalation. Importantly, the protocol provides 3-component coupling products in preference to a variety of 2-component undesired byproducts.

Koecher, S. S.; Heydenreich, T.; Zhang, Y.; Reddy, G. N. M.; Caldarelli, S.; Yuan, H.; Glaser, S. J. published an article about the compound: 2,3-Dibromopropionic acid( cas:600-05-5,SMILESS:O=C(O)C(Br)CBr ).Name: 2,3-Dibromopropionic acid. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:600-05-5) through the article.

Here the authors study the optimum efficiency of the excitation of maximum quantum (MaxQ) coherence using anal. and numerical methods based on optimal control theory. The theor. limit of the achievable MaxQ amplitude and the min. time to achieve this limit are explored for a set of model systems consisting of up to five coupled spins. In addition to arbitrary pulse shapes, two simple pulse sequence families of practical interest are considered in the optimizations. Compared to conventional approaches, substantial gains were found both in terms of the achieved MaxQ amplitude and in pulse sequence durations. For a model system, theor. predicted gains of a factor of three compared to the conventional pulse sequence were exptl. demonstrated. Motivated by the numerical results, also two novel anal. transfer schemes were found: Compared to conventional approaches based on nonselective pulses and delays, double-quantum coherence in two-spin systems can be created twice as fast using isotropic mixing and hard spin-selective pulses. Also in a chain of three weakly coupled spins with the same coupling constants, triple-quantum coherence can be created in a time-optimal fashion using so-called geodesic pulses.
