One-pot oximation–Beckmann rearrangement of ketones and aldehydes to amides of industrial interest: Acetanilide, caprolactam and acetaminophen [PDF]
, 1924 High yielding one-pot oximation–Beckmann rearrangement of ketones to amides in ktrifluoroacetic acid has been conducted on several ketones and aldehydes. The substrate reactivity showed to depend on both oximation and Beckmann rearrangement reaction rate.

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.A metal‐free nitrosation process enables direct C–H functionalization of polyethylene (PE) with high selectivity, producing either oxime‐ or carbonyl‐functionalized polymers. Using t‐BuONO under visible light or thermal conditions, the process operates in both lab‐scale and industrial settings.
