“…sodium sulde, cystine etc) under solvent-free mechanochemical milling conditions. [8][9][10] This method afforded monodisperse NPs of group II-VI metal chalcogenides. Such a bottom-up mechanochemical approach to NP synthesis is based on self-assembly processes, rather than particle comminution.…”

Mechanochemical synthesis of Au, Pd, Ru and Re nanoparticles with lignin as a bio-based reducing agent and stabilizing matrix

A versatile, low-energy and solvent-free method to access nanoparticles (NPs) of four different transition metals, based on a bottom-up mechanochemical procedure involving milling of inorganic precursors, is presented. Lignin, a biomass waste, was used effectively as a reducing agent, for the first time in a mechanochemical context, to access MNPs where M = Au, Pd, Ru, Re. A series of metal precursors was used for this reaction and their nature was shown to be integral in determining whether NPs became incorporated within the organic lignin matrix, M@lignin, or not. Specifically, organometallic precursors resulted in extensive encapsulation of the NPs, as well as improved control over their size and shape, while ionic precursors afforded matrix-free NPs. The resulting NP-containing composites were characterized through Fourier-transform infrared attenuated total reflectance (FTIR-ATR) spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and powder X-ray diffraction (PXRD). This mechanochemical grinding method for accessing M@lignin (M = Au, Pd, Ru and Re) is significantly more sustainable than the traditional solvent batch syntheses of metal NPs because it relies on the use of a biomass-based polymer, it is highly atom economical, it eliminates the need for solvents and it reduces drastically the energy input.

“…One may break the applications discussed in FD170 into perhaps ve categories: (1) inorganic compounds, metal coordination and organometallic complexes and extended coordination polymers (e.g., MOFs); [40][41][42][43] (2) organic synthesis with the making and breaking of covalent bonds; 41,[44][45][46][47] (3) supramolecular and pharmaceutical reactions and the making of co-crystals; 37,42,48 (4) inorganic and organic nanomaterials; 39,40,[49][50][51] and (5) polymer chain scission, intra-and inter-chain reactions.

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 and engineering: from metallurgists to polymer scientists to synthetic organic and inorganic chemists to cellular biologists. Connections among the different subfields of mechanochemistry (tribochemistry, trituration, macromolecular, and sonochemistry) are drawn out and the common themes and open questions are considered.

A versatile and robust mechanochemical route to Aldehyde–Schiff base conversions has been established for a broad range of aldehydes via a simple cogrinding in mortar with a pestle under a solvent‐free, as well as solvent‐assisted, environment. The extent of amines reactivity under these conditions has also been explored, along with an examination of the possible connection between reactivity and electronic substituent effects. Results obtained demonstrated that the solvent‐free mechanochemical conversion of p‐toluidine and aromatic aldehydes to the corresponding Schiff bases proceeded more smoothly than the corresponding synthesis with 4‐aminobenzonitrile. The present approach not only provides good to excellent yields but also eliminates the disadvantages of the traditional synthesis of Schiff bases, such as the use of hazardous solvents, more or less demand of expensive catalysts, and looking for optimization on reaction conditions.
