The axially dissymmetric chiral Schiff base ligand 10, prepared by the reaction of (R)-(+)-1,1?-binaphthyl-2,2?-diamine with (R)-(+)-2,2?-dihydroxy-[1,1?]-binaphthalenyl-3-carbaldehyde, is a fairly effective chiral ligand for the catalytic asymmetric addition reaction of diethylzinc to aldehydes.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2.

The reaction of [Os3(MeCN)2(CO)10] with 2,2?-diamino-l,1?-binaphthalene (H2binam) affords the coordinatively unsaturated trinuclear derivative [Os3(mu-H)(mu3-eta2-Hbinam-N,C)(CO)9 ] (1), which contains a C-metalated Hbinam ligand attached to an Os atom through an NH2 group and to the remaining two Os atoms through the metalated C atom. The unsaturation of 1 is somewhat relieved by a weak interaction of a naphthalene C=C double bond with an Os atom. Curiously, treatment of [Ru3(MeCN)2(CO)10] with H2binam does not give the ruthenium analogue of 1. The stepwise treatment of [Ru3(CO)12] with LiHbinam and [HOEt2][BF4] leads to [Ru3(mu-H)(mu-eta1-Hbinam-N)(CO)10] (2), in which an N-metalated Hbinam acts as an edge-bridging amido ligand. Complex 2 reacts with bis(diphenylphosphanyl)methane (dppm) to give [Ru3(mu-H)2(mu3-eta2-binam-C,N )(mu-eta2-dppm-P,P)(CO)7] (3). This complex contains a doubly C- and N-metalated binam ligand attached to a Ru atom through the metalated C atom and to the remaining two Ru atoms through the metalated NH fragment. Compounds 1 and 3 are the first examples of C-metalated derivatives of H2binam.

A mild synthesis of a series of phenanthrenes with different substituents on the phenanthrene ring is described. The method involves intramolecular oxidative coupling of a variety of 1,2-diarylethylene derivatives in the presence of m-chloroperoxybenzoic acid (m-CPBA) in trifluoroacetic acid (TFA) to yield phenanthrenes in high yields. The present approach solves a key step for the synthesis of polycyclic structures related to an alkaloid tylophorine.

Reference of 4488-22-6, An article , which mentions 4488-22-6, molecular formula is C20H16N2. The compound – [1,1′-Binaphthalene]-2,2′-diamine played an important role in people’s production and life.

A series of chiral Schiff bases, 2,2?-bis(3-R1-5-R 2-2-hydroxybenzylideneamino)-1,1?-binaphthyl H2L (R2 = Cl, R1 = Cl, Me, Et or NO2; R2 = Me, R1 = But; R2 = NO2, R1 = H, Me, Et, Pri, But or Cl), and their complexes [CuL1] 1 and [Mn2L12(OMe)2] 2 (R1 = R2 = Cl) have been prepared. The crystal structure of the racemic form of 1 has been determined. Complex 1 is an active catalyst for the oxidation of alkenes by tertbutyl hydroperoxide. On the contrary, 2 is inert towards alkene epoxidation by PhIO. However, upon mixing Mn(O2CMe)3·xH2O and H2L in acetonitrile a green solution was obtained which could effect asymmetric epoxidation of alkenes by PhIO. The effects of the steric and electronic effects of the R1 and R2 substituents, temperature, and the addition of donors like N-methyl- and 2-methyl-imidazole and pyridine N-oxide on the catalytic activity of the MnIII + (S)-H2L systems towards alkene epoxidation have been investigated. When R1 = Et and R2 = NO2 the best enantiomeric excesses of 58 and 43% were found for epoxidation of cis-beta-methylstyrene to (1S,2R)-cis-beta-methylstyrene oxide and 4-chlorostyrene to 4-(S)-chlorostyrene oxide respectively.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4488-22-6, help many people in the next few years., Reference of 4488-22-6

Titanium and zirconium complexes of bispicolinic amides catalyze the ring opening of cyclohexene oxide with trimethylsilyl azide as nucleophile.The product, 1-azido-2-trimethylsilyloxycyclohexane, was obtained in up to 71percent enantioselectivity when a catalyst prepared from (S,S)-N,N’-bis(2-pyridinecarboxamide)-1,2-diphenylethane and zirconium tetra-t-butoxide was employed under optimum conditions, which included the addition of a small amount of diethylamine in the catalyst preparation step.The nature of the catalyst is still unknown, but it seems probable that oligomeric metal species are involved.

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, Computed Properties of C20H16N2

Binaphthyldiamino, ethyldiamino and cyclohexyldiamino Schiff bases can catalyze the reaction of epoxides with carbon dioxide in the presence of catalytic amounts of various organic bases to give the corresponding cyclic carbonates in high yields. The simplest binaphthyldiamino Schiff base, derived from the reaction of binaphthyldiamine with salicylaldehyde, gave the highest yield of cyclic carbonate. This catalytic system can be further simplified by use of a phenol instead of the Schiff base to give the corresponding cyclic carbonates in high yields as well. Mechanistic insights were obtained based on a deuterium labeling experiment, The reaction of aziridines with CO2 and epoxide with CS2 were also examined under the same reaction conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C20H16N2, you can also check out more blogs about4488-22-6

Binaphthyl stabilized Pt nanoparticles (Pt-BNP) have been synthesized, characterized, and utilized as an efficient heterogeneous catalyst for chemoselective reduction of nitroarenes at room temperature in water. Several sensitive functional groups like ketone, ester, acid, amide, halides, and nitrile were well tolerated in this chemoselective reduction. The Pt-BNP catalyst was quantitatively recovered without any major change in particle size and reactivity and then efficiently reused for five catalytic cycles.

(Chemical Equation Presented) A short concise route to beta- aminophosphine boranes is presented via the desymmetrization of prochiral phosphine boranes, forming P-chirogenic aldehydes that are rapidly transformed to the target compounds employing reductive amination under microwave irradiation. This sequence provides a modular route to P-chirogenic P,N ligands, and in addition, the intermediate aldehydes are versatile P-chiral building blocks for ligand design in general. An alternative pathway via the corresponding alpha-carboxyphosphines is also described. The ligands were subsequently evalutated in the asymmetric conjugate addition of diethylzinc to trans-beta-nitrostyrene.
