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.

Solution Routes

A simple solution route employing the reaction of magnesium acetate tetrahydrate ((CH3COO)2Mg.4H2O) and hexamethylenetetramine (C6H12N4) has been demonstrated to successfully grown MgO thin film on both Mg and MgO substrates at two different temperature i.e 90 °C and 150 °C for 4 h. Morphological observations revealed that the porous structure of MgO film was obtained on Mg substrate while sheet-like structure film was observed when using MgO substrate. EDX indicated only Mg and O were present in all films. The MgO bandgap obtained varies with type of substrate used and temperature. The MgO film growth on Mg substrate bandgap increased from 5.18 eV to 5.27 eV with temperature increased from 90 °C to 150 °C. Similar increased was also observed with MgO film growth on MgO substrate. However the results obtained are well below of MgO bulk energy bandgap. This was probably due to non-stoichiometry of deposited layers and crystallinity of the samples as shown by EDX and XRD results respectively.
