Synthetic Route of 3779-42-8, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 3779-42-8, name is 3-Bromo-N,N,N-trimethylpropan-1-aminium bromide. In an article，Which mentioned a new discovery about 3779-42-8

A novel asymmetrical gemini ionic liquid, 1-(3-(trimethylammonio)prop-1-yl)-3-methylimidazolium bis(dicyanamide) ([N111C3MIM][N(CN)2]2), was synthesized and characterized by 1H NMR, 13C NMR. Thermal stability of [N111C3MIM][N(CN)2]2 was investigated through thermogravimetric analysis under pure nitrogen atmosphere. Heat capacity of pure [N111C3MIM][N(CN)2]2 was measured using differential scanning calorimetry in the temperature range 298.15?423.15 K and enthalpy HT-H298.15K, and entropy ST-S298.15K were obtained. Densities and viscosities were measured for the binary system of [N111C3MIM][N(CN)2]2 and isopropanol (IPA) over the entire range of mole fractions at various temperatures from 283.15 to 333.15 K under the pressure of 0.101 MPa. Moreover, the excess molar volumes (VmE) and the viscosity deviations (Deltaeta) for the binary mixtures were determined and well fitted to the Redlich?Kister polynomials. The negative values of VmE and Deltaeta result from strong self-association and weak hydrogen bonding interaction between the molecules of [N111C3MIM][N(CN)2]2 and IPA. Excess Gibbs energy of activation (DeltaG*E) of viscous flow for the present binary mixtures were also calculated. Results have been discussed in terms of molecular interactions and structures.

In a article，once mentioned of 55515-98-5

The development of a method for the optimization of chiral ligands for the steric steering of enantioselective Cu-catalyzed conjugate additions of Zn-alkyls to enones is described. The method is based on combinatorial principles and solid-phase techniques. It includes the combinatorial synthesis of chiral bispidine-derived ligands embodying a phosphoramidite group on the solid phase and their investigation in immobilized form in the conjugate addition of ZnEt2 to cyclohexenone as test reaction. The best identified ligands were also synthesized separately and investigated in its soluble form. The results obtained for the polymer-bound ligands correctly mirrored the performance of the soluble ligands. The library embodied members giving ee values varying between 3 and 67%. The “positional scanning” approach proved to be invalid for the study of the ligand system, indicating that this approach in general should be applied with care. Taken together, the method allowed for rapid and efficient optimization of the ligands and led to the development of the first enantioselective, Cu-catalyzed conjugate addition reaction with a polymer-bound ligand.

New approach is developed to the synthesis of cyclic amino acids derivatives. Unsaturated tertiary amines react with ethyl diazoacetate under the catalysis by copper catalyst Cu(F3acac)2 leading to the formation of products of [2,3]-sigmatropic rearrangement which via the metathesis of double bonds undergo a ring closure. The subsequent hydrogenation of compounds obtained furnished esters of 6- and 7-membered cyclic alpha-amino acids. Besides the racemic also optically active compounds were obtained, in particular, esters of (R)- and (S)-pipecolic acid.

In a Article, authors is Zhao, Xiaowei，once mentioned of 20439-47-8

Four platinum(IV) complexes containing intercalating ligands [1,10-phenanthroline (phen) and 2,2?-bipyridine (bpy)] and ancillary ligands [(1S,2S)-diaminocyclohexane (SS-DACH) and (1R,2R)-diaminocyclohexane (RR-DACH)] were synthesized and characterized by 1H nuclear magnetic resonance, electrospray ionization mass spectrometry, X-ray crystal structure analysis, elemental analysis, ultraviolet absorption spectroscopy, circular dichroism spectroscopy, and electrochemical analysis. The reactions between [Pt(phen)(SS-DACH)Cl2]2+ and glutathione and Ac-CPFC-NH2 were investigated by high-performance liquid chromatography. [Pt(phen)(SS-DACH)Cl2]2+ was reduced to its corresponding Pt(II) complex [Pt(phen)(SS-DACH)]2+, while glutathione and Ac-CPFC-NH2 were oxidized to glutathione-disulfide and a peptide containing an intramolecular disulfide bond, respectively. The cytotoxicities of the Pt(IV) complexes against a human non-small cell lung cancer cell line (A549) and the corresponding cisplatin-resistant cell line (A549cisR) were evaluated. These Pt(IV) complexes showed a higher activity toward A549 and A549cisR than did cisplatin. Also, the cytotoxicities of the Pt(IV) complexes were higher for A549cisR than for A549 cells. Moreover, the cytotoxicities of the (SS-DACH)-liganded platinum complexes were higher than those of the (RR-DACH)-liganded platinum complexes in either A549 or A549cisR cells. Phen-liganded platinum complexes were more cytotoxic than the bpy-liganded platinum complexes. The cytotoxicities of these Pt(IV) complexes had no correlation with reduction potentials.

The unique nature of the alumina-mediated cyclodehydrofluorination gives the opportunity to execute the preprogrammed algorithm of the C?C couplings rationally built into a precursor. Such multi-assemblies facilitate the construction of the carbon-skeleton, superseding the conventional step-by-step by the one-pot intramolecular assembly. In this work, the feasibility of the alumina-mediated C?F bond activation approach for multi-assembly is demonstrated on the example of a fundamental bowl-shaped polycyclic aromatic hydrocarbon (diindenochrysene) through the formation of all ?missing? C?C bonds at the last step. Beside valuable insights into the reaction mechanism and the design of the precursors, a facile pathway enabling the two-step synthesis of diindenochrysene was elaborated, in which five C?C bonds form in a single synthetic step. It is shown that the relative positions of fluorine atoms play a crucial role in the outcome of the assembly and that governing the substituent positions enables the design of effective precursor molecules ?programmed? for the consecutive C?C bond formations. In general, these findings push the state of the field towards the facile synthesis of sophisticated bowl-shaped carbon-based nanostructures through multi-assembly of fluoroarenes.
