Nickel-mediated cross-coupling via C-O activation assisted by organoaluminum

We report the alkylation and arylation cross-coupling of aryl ethers based on C-O bond activation using a nickel catalyst and organoaluminum reagents. Ni(cod)(2) in combination with 1,2-bis(dicyclohexylphosphino)ethane ligand in toluene solution at 130 degrees C are the best conditions. The naphthyl ether or methoxy pyridine derivatives are suitable substrates for alkylation and arylation reaction with a wider scope of aluminum reagents in good yields. Computational analysis on the pyridine substrate is provided to help delineate the mechanistic pathway and demonstrate the important aspects of the cooperative interaction bimetallic catalysis. First, the coordination of AlMe3 to the O atom of pyridine is essential for C-O activation. Second, the beta-H transfer from methoxy to pyridine could be discouraged through the use of bidentate phosphine as a ligand. Finally, excess AlMe3 reagent is critical for facilitating a reductive elimination process.

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. you can also check out more blogs about 26218-75-7. Recommanded Product: 26218-75-7.

Thermal, SEM, AFM, BET and biological analysis of newly synthesized Fe2+/Fe3+ based MOIFs

Herein we report the thermal, morphological, topographical, gas adsorption and biological activities of newly synthesized [Fe(CN)(6)](4-)/[Fe(CN)(6)](3-) based MOIFs using Differential Scanning Colorimetry (DSC), Scanning Electron Microscope (SEM), BET (Brunauer, Emmett and Teller) and spectrophotometric methods. Thermal analysis revealed an effect of MOIFs alkyl chain on their heat holding capacity as a function of temperature. Nitrogen adsorption method was applied for surface and apparent cross-sectional area determination within MOIF ionic assembly. The DNA binding activity (DBA) of as prepared MOIFs was found in 40% order, computed using Ameta-Hyper-Hypochromic model. The increments and decrements in DNA helix axial length were conferred by hydrophobic (Hb)/hydrophilic (Hp) interactions, attributing for corresponding hyper/hypo chromic effect. Considerable anticancer activities of +2 and +3 Fe oxidation states (evaluated on MCF-7 cell line) for the DTAB stabilized MOIFs, were noticed. Apart from this, the free radical antioxidant activity of MOIF has also been investigated, found as directly varying with the alkyl chain lengths. A free radical trapping mechanism is suggested on the basis of H-b-H-b and Hp-Hp interactions. (C) 2019 Published by Elsevier B.V.

Synthetic Route of 26218-75-7, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 26218-75-7, name is Methyl 6-bromopicolinate. This compound has unique chemical properties. The synthetic route is as follows.

In a nitrogen atmosphere, 30 mL of 3 M methylmagnesium iodide/diethyl ether was added to 300 mL of diethyl ether solution of 8.72 g of methyl 6-bromopyridine-2-carboxylate. Water and 2 N hydrochloric acid were added to the reaction liquid, and extracted with ethyl acetate. This was washed with aqueous saturated sodium hydrogencarbonate solution and saturated saline water, and dried with anhydrous magnesium sulfate. The solvent was evaporated away under reduced pressure to obtain crude 2-(6-bromo-2-pyridinyl)-2-propanol as a yellow oily substance. 1H-NMR (400 MHz, CDCl3) delta: 7.56 (1H, t, J=7.8 Hz), 7.38 (1H, dd, J=7.8, 1.0 Hz), 7.36 (1H, dd, J=7.8, 1.0 Hz), 1.55 (6H, s). ESI-MS Found: m/z[M+H]+ 216, 218.
