In-situ monitoring of polymer mechanochemistry: what can be learned from small molecule systems
Using mechanical energy to drive chemical transformations is an exciting prospect to improve the sustainability of chemical reactions and to produce products not achievable by more traditional methods. In-situ monitoring of reaction pathways and chemical

Bayesian Optimization of Solvent‐Free Thermal Amidation via Reactive Extrusion
Thermal amidation between a carboxylic acid and an amine was successfully conducted in an extruder in the absence of solvent, coupling agent, or catalyst, relying on an adapted Bayesian Optimization protocol. Active pharmaceutical ingredient moclobemide was synthesized on a larger scale, achieving excellent yield and low Process Mass Intensity (PMI ...

Moving mechanochemistry forward [PDF]
Arguably mechanochemistry is one of the oldest, and at the same time one of the newest, areas of chemistry. One of the oldest, because it has been theorized that early hominids were able to develop rapidly due to their ability to heat and mechanically ...

Mechanochemical Hydrodeoxygenations
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using

Polymer Mechanochemistry: Force Enabled Transformations [PDF]
In this viewpoint, we highlight the ability of mechanical force to overcome the limitations associated with using thermal or photochemical stimuli to facilitate chemical transformations. Emphasis will be directed toward examples of new chemical reactions

Solvent-free sonochemistry: Sonochemical organic synthesis in the absence of a liquid medium
Sonochemistry, i.e., the application of mechanical energy in the form of sound waves, has recently been recognised for its similarity to mechanochemistry and is now included under the umbrella term of mechanochemistry.

Mechanochemistry of degree two
Abstract We simplify some proposed formulas for hydrostatic pressure on a molecule by G. Subramanian, N. Mathew and J. Leiding, J. Chem. Phys. 143, 134109 (2015). We apply the formulas to an artificial triatom ABC whose potential energy surface is formed by a combination of Morse curves.
