Mechanochemical Synthesis of Catalytic Materials [PDF]
Chemistry – A European Journal, 2021 AbstractThe mechanochemical synthesis of nanomaterials for catalytic applications is a growing research field due to its simplicity, scalability, and eco‐friendliness. Besides, it provides materials with distinct features, such as nanocrystallinity, high defect concentration, and close interaction of the components in a system, which are, in most cases,

Mechanochemical synthesis of inverse vulcanized polymers [PDF]
Nature Communications, 2022 Abstract Inverse vulcanization, a sustainable platform, can transform sulfur, an industrial by-product, into polymers with broad promising applications such as heavy metal capture, electrochemistry and antimicrobials. However, the process usually requires high temperatures (≥159 °C), and the crosslinkers needed to

Mechanochemical Synthesis of Short DNA Fragments [PDF]
Chemistry – A European Journal, 2020 We report the general and rapid synthesis of short DNA fragments of controllable sequence and length using multi-step, one-pot mechanochemical reactions, without bulk solvent or the need to isolate intermediates. We demonstrate, for the first time, the multi-step ball milling synthesis of DNA dimers and trimers via phosphoramidite and H-phosphonate ...

Mechanochemical Synthesis of Fluorinated Imines
Molecules, 2022 A number of imines, including 12 new compounds, previously not reported in the literature, derived from variously fluorinated benzaldehydes and different anilines or chiral benzylamines were synthesized by a solvent-free mechanochemical method, which was

Extending mechanochemical porphyrin synthesis to bulkier aromatics: tetramesitylporphyrin
Beilstein Journal of Organic Chemistry, 2019 Aldehydes with bulky substituents in the ortho-positions have been historically difficult in porphyrin synthesis, presumably owing to steric hindrance around the reactive site.

Mechanochemical synthesis of nanoparticles
Journal of Materials Science, 2004 The results of recent investigation of the mechanochemical synthesis of inorganic nanoparticles are reviewed. It was demonstrated that, by selecting suitable chemical reaction paths, stoichiometry of starting materials and milling conditions, mechanochemical processing can be used to synthesise a wide range of nanocrystalline particles dispersed within

Mechanochemically‐Assisted Synthesis of Polyimides [PDF]
ChemSusChem, 2021 AbstractPolyimides were obtained in 99 % yield in under 1 h through the “beat and heat” approach, involving solvent‐free vibrational ball milling and a thermal treatment step. The influence of a plethora of additives was explored, such as Lewis acids, Lewis bases, and dehydrating agents, and the mechanochemical reaction was identified to run via a ...

Mechanochemically Assisted Synthesis of Hexaazatriphenylenehexacarbonitrile [PDF]
The Journal of Organic Chemistry, 2021 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile (HAT CN) was synthesized mechanochemically at room temperature. The coupling of hexaketocyclohexane and diaminomaleonitrile was conducted in 10 min by vibratory ball milling. The effects of milling parameters, acids, dehydrating agents, and liquid-assisted grinding were rationalized.
