Quantitative and Mechanistic Mechanochemistry in Ferrocene Dissociation

Mechanochemistry

The scientific community’s general interest in using mechanical energy to trigger or facilitate chemical reactivity has been growing at a speedy pace. In particular, in recent years, organic chemistry has witnessed a constant flow of examples where the use of mechanochemical techniques proved not only to outperform traditional solution-based methodologies, but also enabled access to otherwise i...

3. Apparent and hidden mechanochemistry

Two phenomena will be considered. Phase transformations (PTs) and chemical reactions (CRs) under compression and shear of materials in rotational diamond anvil cell (RDAC) represent examples of apparent effects of plastic shear. We recently predicted the new phenomenon that crystal-crystal and crystalamorphous PTs can occur through virtual melting (VM) significantly below (> 1000K!) the melting...

Ring Rotation in Ferrocene and Ferrocene-containing Polymers

Ferrocene is an organometallic molecular sandwich complex with an iron atom coordinated between two cyclopentadienyl rings. The reorientation of these rings in a process of rotational jump diffusion between multiple equilibrium sites on a circle is investigated using quasielastic neutron time of flight and backscattering spectroscopy experiments. Existing results on the ring rotation in bulk, c...

Mechanochemistry and sonochemistry: concluding remarks.

This paper offers a perspective on mechanochemistry and offers summarizing commentary on the Faraday Discussion 170, "Mechanochemistry: From Functional Solids to Single Molecules". The connection between the mechanical and the chemical worlds dates back to our earliest written records and beyond, but its renaissance over the past decade or so has had an impact on a huge swathe of modern science...
