A process for producing an amine which is characterized by reacting an imine with a nucleophilic compound (except a trialkylsilyl vinyl ether) in the presence of a phosphoric acid derivative represented by the formula (1): wherein A1 represents a spacer; X1 and X2 represent each independently a divalent nonmetal atom or a divalent nonmetal atomic group; and Y1 is oxygen or sulfur. The invention provides a process by which amines (particularly optically active amines) useful as intermediates of medicines, agricultural chemicals, or the like can be produced without special post-treatment in high yield at high optical purity; and phosphoric acid derivatives (particularly optically active phosphoric acid derivatives) useful in the production of the amines.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, category: chiral-catalyst.

The synthesis and characterization of the open-chain and cyclic sapphyrin dimers 2-4 and 7, bearing various bisamide spacers is reported. This family of receptors was shown to display excellent recognition properties for various dicarboxylate anions, as judged from mass spectrometric analyses, U-tube aqueous I/CH2Cl2/aqueous II through-model-membrane transport experiments, and equilibrium binding studies. These latter were carried out in either methanol or dichloromethane using 1H or 2H NMR and visible spectroscopic titrations. The flexible, first-generation system 2, featuring a 1,3-bisamidopropane spacer was found to display a high affinity for dicarboxylate anions even in polar solvents, such as methanol. Within a range of substrates, this receptor showed a strong preference toward linear over bent, and aromatic over aliphatic dicarboxylate anions, a fact that is readily rationalized in terms of extra, stabilizing Pi-Pi, C-H···pi or C-H···N interactions. This latter C-H···N hydrogen-binding motif was observed in the single crystal structure of the 1:1 complex formed between benzoate anion and the monoprotonated form of sapphyrin 1a. The second-generation, open-chain chiral sapphyrin dimers 3 and 4 (containing (1S,2S)-1,2-bisamidocyclohexane and (S)-2,2′-bisamido-1,1′-binaphthalene chiral auxiliaries, respectively) were found to form strong complexes with N-carbobenzyloxy-protected aspartate and glutamate anions (K(a), values are on the order of 104-105 M-1 in 19:1 (v/v) dichloromethane-methanol)), and displayed a preference for glutamate over aspartate, with receptor 4 showing a modest level of enantiomeric selectivity. The cyclic dimer 7 binds these anions less effectively, but displays excellent chiral discrimination between the D- and L-antipodal forms of N-carbobenzyloxy-protected glutamate anion.

It has been shown that catalytic amounts (10-20 mol %) of novel axially chiral bis-arylthioureas promote the asymmetric organocatalytic Friedel-Crafts type addition of indole and N-methylindole to nitroolefins. The optimum catalyst is capable of promoting the reaction between challenging substrates such as N-methylindole and nitroolefins bearing aliphatic beta-substituents with enantioselectivity unprecedented for an organocatalytic system.

Directing group-assisted regioselective C-H olefination with electronically biased olefins is well studied. However, the incorporation of unactivated olefins has remained largely unsuccessful. A proper mechanistic understanding of olefination involving unactivated alkenes is therefore essential for enhancing their usage in future. In this Article, detailed experimental and computational mechanistic studies on palladium catalyzed C-H olefination with unactivated, aliphatic alkenes are described. The isolation of Pd(ll) intermediates is shown to be effective for elucidating the elementary steps involved in catalytic olefination. Reaction rate and order determination, control experiments, isotopic labeling studies, and Hammett analysis have been used to understand the reaction mechanism. The results from these experimental studies implicate beta-hydride elimination as the rate-determining step and that a mechanistic switch occurs between cationic and neutral pathway. Computational studies support this interpretation of the experimental evidence and are used to uncover the origins of selectivity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.name: [1,1′-Binaphthalene]-2,2′-diamine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4488-22-6, in my other articles.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2. In a Article，once mentioned of 4488-22-6, name: [1,1′-Binaphthalene]-2,2′-diamine

Biologically important bisindolylmethanes are synthesized in a domino fashion by using an iron(II) chloride-(±)-1,1?-binaphthyl-2, 2?-diamine [FeCl2-(±)-BINAM] complex as the catalyst. This method proceeds via oxidation of a primary alcohol into the corresponding aldehyde followed by nucleophilic addition of an indole in the presence of the catalyst. A reaction intermediate is synthesized separately and converted into the bisindolylmethane product under the same reaction conditions as support for the proposed mechanism.

Electric Literature of 4488-22-6. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine. In a document type is Article, introducing its new discovery.

The novel diamine-bis(ether-phosphine)ruthenium(II) complexes Cl 2Ru(eta1-Ph2PCH2-CH 2OCH3)2(diamine)2(3L 1-3L11) have been obtained by reaction of equimolar amounts of Cl2Ru(P?O)2 (2) with the respective diamines L1-L11 in good yields. X-ray structural investigations of 3L2 and 3L8 show monoclinic unit cells with the space group P21/c. The octahedrally coordinated ruthenium atoms have each two trans-chlorides and cis-phosphines which is in agreement with NMR studies in solution. With the exception of 3L4 all mentioned ruthenium complexes are highly catalytically active in the hydrogenation of the alpha,beta-unsaturated ketone trans-4-phenyl-3-butene- 2-one. In most cases the conversions and selectivities toward the formation of the unsaturated alcohol trans-4-phenyl-3-butene-2-ol were 100% with high turnover frequencies under mild conditions.
