Direct visualization of a mechanochemically induced molecular rearrangement

Recent progress in the field of mechanochemistry has expanded the discovery of mechanically induced chemical transformations to several areas of science. However, a general fundamental understanding of how mechanochemical reactions by ball milling occur has remained unreached. For this, we have now implemented in‐situ monitoring of a mechanochemically induced molecular rearrangement by synchrotron X‐ray powder diffraction, Raman spectroscopy, and real‐time temperature sensing. The results of this study demonstrate that molecular rearrangements can be accomplished in the solid- state by ball milling, and how in‐situ monitoring techniques enable the visualization of the changes occurring at the exact instant of a molecular migration. In this study, during the mechanochemical benzil‐benzilic acid rearrangement.
