Redox reactions of small organic molecules using ball …

Specifically, we envisioned that the agitation of piezoelectric materials (23–35) via ball milling could generate temporarily highly polarized particles. These particles might act as strong reductants to transfer electrons to small organic molecules, followed by oxidative quenching of a donor, thereby inducing the selective formation of bonds in a manner analogous to photoredox catalysis ...
