On September 30, 2021, Rawat, Vishal Kumar; Higashida, Kosuke; Sawamura, Masaya published an article.Computed Properties of 93-04-9 The title of the article was Nickel-Catalyzed Homocoupling of Aryl Ethers with Magnesium Anthracene Reductant. And the article contained the following:

Nickel-catalyzed reductive homocoupling of aryl ethers has been achieved with Mg(anthracene)(thf)3 as a readily available low-cost reductant. DFT calculations provided a rationale for the specific efficiency of the diorganomagnesium-type two-electron reducing agent. The calculations show that the dianionic anthracene-9,10-diyl ligand reduces the two aryl ether substrates, resulting in the homocoupling reaction through supply of electrons to the Ni-Mg bimetallic system to form organomagnesium nickel(0)-ate complexes, which cause two sequential C-O bond cleavage reactions. The calculations also showed cooperative actions of Lewis acidic magnesium atoms and electron-rich nickel atoms in the C-O cleavage reactions. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Computed Properties of 93-04-9

Salamanca, Vanesa; Albeniz, Ana C. published an article in 2021, the title of the article was Faster palladium-catalyzed arylation of simple arenes in the presence of a methylketone: beneficial effect of an a priori interfering solvent in C-H activation.Electric Literature of 91-16-7 And the article contains the following content:

The arylation of arenes with no directing groups (non-chelate assisted) was carried out using the cooperating ligand [2,2′-bipyridin]-6(1H)-one (bipy-6-OH), the use of a moderately coordinating solvent allows a decrease of the amount of arene used. Moreover, for the least coordinating arenes, the co-solvent produced a significant accelerating effect by altering the concentration and relative stability of relevant metal species in the catalytic cycle as well as the catalyst resting state. t-Bu Me ketone (pinacolone) was one of the most effective co-solvents: Even if the ketone C-H bond cleaves easily, the final products were determined by the reductive elimination step (the product-forming step) so the target biaryl products were selectively observed The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Electric Literature of 91-16-7

The regiodivergent catalytic dehydrogenative cross-coupling reactions at both sp2 and sp3 hybridized carbons of aromatic compounds are particularly challenging. Herein, the finding of transient directing group controlled regiodivergent C(sp3)-C(sp2) and C(sp2)-C(sp2) cross-coupling in the o-Me benzaldehyde frameworks 2-CH3RC6H3CHO (R = H, 6-Me, 4-Br, 4,6-(CH3)2, etc.) is reported. Catalyzed by palladium, using K2S2O8 or [F+] reagents as by-standing oxidants and unactivated arenes R1C6H5 (R1 = H, OEt, Me, Cl, etc.) as substrates/solvents, various benzyl benzaldehydes RC6H3CHO-2-CH2C6H4R1 or Ph benzaldehydes R-2-MeC6H2CHOC6H4R1 were prepared A mechanism study indicated that the regiospecificity is dominated by the [5,6]-fused palladacycle or [6,5]-fused palladacycle intermediates, which are generated from Pd-chelation with specified transient directing groups and further C-H activations. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Category: ethers-buliding-blocks

On September 26, 2022, Sudhakaran, Swetha; Siddiki, S. M. A. Hakim; Kitiyanan, Boonyarach; Nomura, Kotohiro published an article.Application In Synthesis of 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was CaO Catalyzed Transesterification of Ethyl 10-Undecenoate as a Model Reaction for Efficient Conversion of Plant Oils and Their Application to Depolymerization of Aliphatic Polyesters. And the article contained the following:

Transesterification of Et 10-undecenoate (derived from castor oil) with cyclohexanemethanol over a CaO catalyst (prebaked at 300°C) gave undec-10-enoate exclusively (yield 92%, selectivity 95-98%) at 100°C, and the activity increased at 120°C with maintaining the high selectivity (97-98%). The transesterification with other alcs., especially primary alcs. (2-ethyl-1-butanol, 1-hexanol, 3-buten-1-ol, and 10-undecen-1-ol), afforded the corresponding esters with high selectivity, indicating the possibility for application of efficient conversion of plant oils to various fine chems. including the monomer for the synthesis of polyesters. Efficient acid-, base-free depolymerization of aliphatic polyesters, poly(ethylene adipate) and poly(butylene adipate), has been demonstrated in this catalysis by transesterification with ethanol and cyclohexanemethanol, affording corresponding adipates and ethylene glycol or butylene glycol exclusively: the reusability of a CaO catalyst has also been demonstrated.

On October 27, 2015, Menk, Florian; Mondeshki, Mihail; Dudenko, Dmytro; Shin, Suyong; Schollmeyer, Dieter; Ceyhun, Oliver; Choi, Tae-Lim; Zentel, Rudolf published an article.Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Reactivity Studies of Alkoxy-Substituted [2.2]Paracyclophane-1,9-dienes and Specific Coordination of the Monomer Repeating Unit during ROMP. And the article contained the following:

The polymerization of alkoxy-substituted [2.2]paracyclophane-1,9-dienes via ring-opening metathesis polymerization (ROMP) to obtain soluble poly(p-phenylenevinylene)s is a versatile method due to its living nature which enables the possibility of block copolymerization and end group modification. However, detailed studies on the reactivity behavior and the polymerization process of alkoxy-substituted [2.2]paracyclophane-1,9-dienes have not been reported so far. Herein we present a detailed study on the varying tendencies of the four isomers of dimethoxy-(2-ethylhexyloxy)-[2.2]paracyclophane-1,9-diene to undergo ROMP. Therefore, we carried out polymerization combining all individual isomers with five different metathesis catalysts and collected initiation and propagation kinetics for various combinations. Furthermore, we revealed a specific coordination of the monomer repeating unit to the catalyst during the polymerization process and succeeded to polymerize not only the pseudogeminal isomers but also one of the pseudo-ortho isomers. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene
