Synthesis of amides via Beckmann rearrangement of ketoximes promoted by cyanuric chloride (TCT)/DMSO under mild conditions has been reported. Conditions of the Beckmann rearrangement, e.g., solvents, the ratios of TCT/DMSO, and the temperature, were investigated using diphenylmethanone oxime as a substrate. The optimized conditions were adopted to afford fourteen amides with yields ranging from 20% to 99%. A plausible mechanism involving an active dimethyl alkoxysulfonium intermediate was proposed according to the mass spectrometry analysis. To our best knowledge, this is the first case of study on Beckmann rearrangement of ketoximes promoted by TCT/DMSO under a mild condition to afford amides efficiently.

A simple, iron-based catalytic system allows for facile Beckmann rearrangement of various oximes. The mild conditions avoid the use of harsh or expensive acids, and the reactions do not require an inert atmosphere. Additionally, a range of amides can be accessed through this transformation.
Selenium-catalyzed deoxygenative reduction of aliphatic nitro compounds with carbon monoxide

A reduction method of aliphatic nitro compounds to oximes using carbon monoxide was developed. When aliphatic nitro compounds were treated with carbon monoxide in the presence of a selenium catalyst, the corresponding oximes were formed in moderate to good yields.
