The geometric and electronic structure of 1,3-dipolar species, in particular of nitrile imines, can be surprisingly intricate. A particular example is the C-phenyl-nitrilimine, which exists as two energy minima that constitute bond-shift isomers. ...

A Mechanistic Perspective on the Mechanochemical Method To Reduce Carbonyl Groups with Stainless Steel and Water
Von Wiley-VCH zur Verfügung gestellt
Mechanochemical reduction of the carbonyl group has been investigated using temperature-controlled mixer mill. The design of solvent-free organic transformation has resulted in increased interest in mechanochemistry, the water-mediated mechanochemical reduction was conducted in a stainless-steel vial. Mechanistic studies suggest that the reduction proceeds through a single electron transfer pathway, with iron and nickel as essential components for the reaction.
Abstract
Mechanochemistry through high-speed ball milling has become an increasingly popular method for performing organic transformations. This newfound interest in high-speed ball milling is in part driven by the benefit of performing reactions in the absence of solvent. Mechanochemical reactions are often conducted in stainless-steel vials with stainless-steel balls. Since stainless steel is made of several readily oxidizable metals (Fe, Cr, and Ni), reduction reactions using water as a hydrogen source were explored using a temperature-controlled mixer mill. Mechanistic studies suggest that the reduction proceeds via a single electron transfer (SET) pathway, with iron and nickel being essential components for the reaction.
