Diaryl ketones from arenes
WebJul 12, 2024 · Abstract The aerobic oxidation of diaryl and aryl (hetero) methylenes into ketones, catalyzed by Ag/C nanoparticles under mild conditions, was successfully developed. This method features a wide scope of substrates, good yields, and uncomplicated recycling of the catalyst. Download to read the full article text References WebWhen aryl alkyl ketones are heated in the presence of elemental sulfur and ammonia, or a primary or secondary amine they undergo a reduction–rearrangement reaction. The carbonyl carbon is reduced to a methylene group and the terminal carbon is oxidized to a thioamide (see Scheme 4 for an example).
