Redox reactions of small organic molecules using ball milling

2019/12/20Specifically, 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

Milling

The controlled reduction of a material's particle size by milling, grinding or micronising to achieve the required end product is a vital commercial process. Whether particle size reduction is required as an economical means of improving solubility, to increase dissolution rates or to improve batch-to-batch consistency and performance, British Rema can offer a solution.
