Hydrogenation reactions are one of the pillars of the chemical industry, with applications from bulk chemicals to pharmaceuticals manufacturing. The ability to selectively add hydrogen across double and/or triple bonds is key in the chemist’s toolbox, and the enabling component in the development of sustainable processes. Traditional solution-based approaches to hydrogenation reactions are tainted by significant consumption of energy and production of solvent waste. This review highlights the development and applications of recently emerged solvent-free approaches to conduct the hydrogenation of organic molecules using mechanochemistry, i.e. chemical transformations induced or sustained by mechanical force. In particular, we will show how mechanochemical techniques such as ball-milling enable catalytic or stoichiometric metal-mediated hydrogenation reactions that are simple, fast, and are conducted under significantly milder conditions compared to traditional solution routes. Importantly, we highlight the current challenges and opportunities in this field, while also identifying exciting cases in which mechanochemical hydrogenation strategies lead to new, unique targets and reactivity.

The complex of boron trifluoride with benzoic anhydride has been prepared. One molecule of anhydride coordinates three molecules of boron trifluoride. The infrared spectrum shows that coordination takes place at the carbonyl groups, whose frequency is lowered some 200 cm−1. There is no trace of the benzoylium cation, C6H5O+. Although the spectra are complex, tentative assignments are made.

The amide bond of acetamide is unaffected by hydrogen exposure, but the hydrogen abstraction on its methyl site activates this molecule to react with other species to extend its size as a first step to form interstellar complex organic molecules.
