The 2Zn(BH4)2 · L compounds were prepared by the reaction of zinc tetrahydroborate with crown ethers, 15-crown-5, 18-crown-6, and dibenzo- 18-crown-6 (L), in diethyl ether or tetrahydrofuran. The products were characterized by chemical, X-ray diffraction, differential thermal analyses, and IR spectroscopy and compared with the complexes Zn(BH4)2· L described previously.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 33100-27-5 is helpful to your research., Reference of 33100-27-5

UV light irradiation of 1-chloro-, 2-chloro-, 1,2-dichloro-, 2,3-dichloro-, and 2,7-dichlorodibenzo-p-dioxin in methanol leads to regioselective homolysis of carbon-oxygen bond from the singlet excited state to undergo rearrangement into chlorinated 2,2?-biphenols. On the contrary, reaction from the triplet excited state of chlorinated dioxins results in selective formation of dechlorinated congeners without altering the dioxin skeleton. Copyright

Periodic mesoporous organosilica (PMO) materials containing methoxy- or methoxyethoxymethyl-ether protected biphenol dopants were synthesized and the protecting groups were cleaved to liberate reactive C2-symmetric diols within the solid-state material. Treatment of the deprotected PMO materials with phosphoryl chloride yielded phosphate ester functional groups predominantly at the exposed biphenol sites, while protected materials showed only surface phosphate species. Since biphenols are closely related to common ligands for asymmetric catalysis, these results open up significant possibilities for the design of chiral recoverable catalysts with chiral groups embedded in the walls of the material.

A series of new chiral mono- or bidentate phosphorus ligands were efficiently prepared through a key intermediate (S)-4-chloro-4,5-dihydro-3H-4-phosphacyclohepta[2,1-a;3,4-a?] binaphthalene and its derivatives. These ligands were applied in the Rh-catalyzed asymmetric hydrogenation of alpha-dehydro amino acids, enol acetates, itaconates, and enamides. Good to excellent enantioselectivities were obtained (up to 99.5% ee).

Related Products 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.

Palladium-catalysed aminocarbonylation of a terpenoic iodoalkene (2-iodo-bornene) model compound with both enantiomerically pure and racemic 2,2?-diamino-1,1?-binaphthalene (BINAM) as the N-nucleophile was carried out. All of the diastereoisomers of the monocarboxamide (N-bornenyl carboxamide) and dicarboxamide (N,N?-dinorbornenylcarboxamide) derivatives were synthesised. The diastereoselectivities of the aminocarbonylation were investigated in both cases: either racemic BINAM was used as the N-nucleophile in the aminocarbonylation of enantiomerically pure 2-iodobornene or racemic iodobornene was aminocarbonylated with enantiomerically pure BINAM with moderate diastereoselectivities. In this way, all possible diastereoisomers of binaphthalene-bornene conjugates were synthesised in moderate to high yields by asymmetric (diastereoselective) aminocarbonylation.

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., Related Products of 4488-22-6

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 21436-03-3, Safety of (1S,2S)-Cyclohexane-1,2-diamine

The structure-activity relationships of bisquinolines, a potentially important group of novel antimalarial drugs, were studied. The high-temperature (180-250C) synthesis of 4-aminoquinolines, including bisquinolines, by nucleophilic displacement was both fast and efficient. Several bisquinolines including (±)-trans-N1,N2-bis(7-trifluoroquinolin-4-yl) cyclohexane-1,2-diamine and 1R,2R-(-)-, 1S,2S-(+)-, (±)-trans- and cis-N1,N2-bis(7-chloroquinolin-4-yl)cyclohexane-1,2-diamine exhibited potent activity against Plasmodium berghei in mice; (+)-trans-N1,N2-bis(7-chloroquinolin-4-yl)cyclohexane-1,2-diamine was orally active. Our results indicate that these compounds conform to a putative receptor for quinoline antimalarials. In addition, a 7-haloquinoline linked by a heterocyclic bridge, at the 4-position, to another heterocycle (such as an acridine at the 9-position) maximally occupies the active site of our postulated target.

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.Safety of (1S,2S)-Cyclohexane-1,2-diamine, you can also check out more blogs about21436-03-3

In an article, published in an article, once mentioned the application of 14098-44-3, Name is Benzo-15-crown-5,molecular formula is C14H20O5, is a conventional compound. this article was the specific content is as follows.category: chiral-catalyst

The reaction of [Zr(TrenDMBS)(Cl)] [Zr1; TrenDMBS=N(CH2CH2NSiMe2But)3] with NaPH2 gave the terminal parent phosphanide complex [Zr(TrenDMBS)(PH2)] [Zr2; Zr?P=2.690(2) A]. Treatment of Zr2 with one equivalent of KCH2C6H5 and two equivalents of benzo-15-crown-5 ether (B15C5) afforded an unprecedented example (outside of matrix isolation) of a structurally authenticated transition-metal terminal parent phosphinidene complex [Zr(TrenDMBS)(PH)][K(B15C5)2] [Zr3; Zr=P=2.472(2) A]. DFT calculations reveal a polarized-covalent Zr=P double bond, with a Mayer bond order of 1.48, and together with IR spectroscopic data also suggest an agostic-type Zr???HP interaction [?ZrPH=66.7] which is unexpectedly similar to that found in cryogenic, spectroscopically observed phosphinidene species. Surprisingly, computational data suggest that the Zr=P linkage is similarly polarized, and thus as covalent, as essentially isostructural U=P and Th=P analogues.
