Stainless‐Steel Ball‐Milling Method for Hydro‐/Deutero‐genation using H2O/D2O as a Hydrogen/Deuterium Source

A one-pot continuous-flow method for hydrogen (deuterium) generation and subsequent hydrogenation (deuterogenation) was developed using a stainless-steel (SUS304)-mediated ball-milling approach. SUS304, especially zero-valent Cr and Ni as constituents of the SUS304, and mechanochemical processing played crucial roles in the development of the reactions.
