Arylacetic acid equivalents bearing a pyridine group undergo C(sp)-H/C(sp)-H cross coupling with diverse methylarenes in the presence of a copper based catalyst system. The reaction proceeds the formation of α-carbonyl radicals giving access to α,β-diarylpropionic acids. Preliminary study suggests that the catalyst system is capable of transforming arylbenzyl ketones into 1,2,3-triaryl ketones.

Decades of research demonstrated that microbes can remediate petroleum-contaminated environments through biodegradation of hydrocarbons. Recent studies have applied signature metabolite analysis to investigate hydrocarbon-contaminated sites, focusing primarily on aquifer systems and metabolites of relatively water-soluble monoaromatic hydrocarbons. However, the number of studies involving non-targeted analysis and identification of individual metabolites in environmental samples is limited.

The protonolysis and redox reactivity of a Ce(IV) carbonate complex supported by the Kläui tripodal ligand [(η-CH)Co{P(O)(OEt)}] (L) have been studied. Whereas treatment of [Ce(L)(CO)] () with RCOH afforded [Ce(L)(RCO)] ( = Me (), Ph (), 2-NOCH ()), the reaction of with PhCHCOH resulted in formation of a mixture of Ce(IV) () and Ce(III) () carboxylate species. In benzene in the dark, was slowly converted into via Ce(IV)-O(carboxylate) homolysis.

The recently developed phenoplast-related polymer, poly(benzofuran--arylacetic acid), presents a versatile molecular structure containing lactone and carboxylic acid functionalities that offer significant flexibility in creating cured materials with tailored properties for diverse applications, wherein also the thermal conductivity is an important factor. This study analyses the possibility of forming amide moieties of poly(benzofuran--arylacetic acid) with diamines resulting in cross-linked products in order to control its thermal properties. The cross-linking process is achieved by utilizing three distinct diamines, 1,6-diaminohexane, -xylylenediamine, and 4,7,10-trioxa-1,13-tridecanediamine, each possessing different degrees of polarity, flexibility, and reactivity.

Sulfonylhydrazones have been proven to be versatile synthetic intermediates in a panel of transformations. However, radical sulfonylation with sulfonylhydrazone as sulfonyl radical source is relatively rare. Here, we found that sulfonylhydrazone can serve as a new sulfonyl radical precursor to couple various partners such as arylacetic acids, ene-yne-ketones, and -quinone methides under copper catalysis and microwave irradiation.
