On December 22, 2021, Rivero-Crespo, Miguel A.; Toupalas, Georgios; Morandi, Bill published an article.Category: ethers-buliding-blocks The title of the article was Preparation of Recyclable and Versatile Porous Poly(aryl thioether)s by Reversible Pd-Catalyzed C-S/C-S Metathesis. And the article contained the following:

Porous organic materials (polymers and COFs) have shown a number of promising properties; however, the lability of their linkages often limits their robustness and can hamper downstream industrial application. Inspired by the outstanding chem., mech. and thermal resistance of the 1D polymer polyphenylene sulfide (PPS), we have designed a new family of porous poly arylthioethers, synthesized via a mild Pd-catalyzed C-S/C-S metathesis-based method, that merges the attractive features common to porous polymers and PPS in a single material. In addition, the method is highly modular, allowing to easily introduce application-oriented functionalities in the materials for a series of environmentally relevant applications including metal capture, metal sensing and heterogeneous catalysis. Moreover, despite their extreme chem. resistance, the polymers can be easily recycled to recover the original monomers, offering an attractive perspective for their sustainable use. In a broader context, these results clearly demonstrate the untapped potential of emerging single-bond metathesis reactions in the preparation of new, recyclable materials. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Category: ethers-buliding-blocks

And the article contained the following:

The sulfonamidyl (hetero)arenes synthesis by the C(sp2)-H amidation from bench-stable amidyl-iminophenylacetic acids was reported. The hypervalent iodine reagents covalently activated iminophenylacetic acids for the facile sulfonamidyl radical generation under mild photocatalytic oxidative conditions. Diversified indoles, pyrroles, imidazopyridines and fused arenes underwent the C(sp2)-H amidation with excellent chemoselectivity and regioselectivity. This reaction performed well under neutral aqueous conditions with potential biol. applications.

Herein, the unprecedented earth-abundant 3D-metal-catalyzed atroposelective direct arylation was reported, furnishing rare atropoisomeric C2-arylated indoles. Kinetic studies and DFT computation revealed an uncommon mechanism for this asym. transformation, with the oxidative addition being the rate- and enantio-determining step. Excellent stereoselectivities were reached (up to 96% ee), while using an unusual N-heterocyclic carbene-ligand bearing essential remote substituent. Attractive dispersion interactions along with pos. C-H—π interactions exerted by the ligand were identified as key factors to guarante the excellent enantioselection.

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.
