“…The dissolution rate of quartz in hydrofluoric acid was also shown to depend critically on the type of mechanical treatment, with vibratory milling yielding slower dissolution kinetics than jet milling ( Heinicke, 1984 ). Similar effects are observed for the formation of a Zn—fumarate metal-organic framework, which forms the tetrahydrate upon intense treatment in a SPEX-8000 mill, but a pentahydrate upon restricted impact treatment or laboratory vibratory ball milling ( Strobridge et al, 2010 ; Tumanov et al, 2012 ). The rate of mechanochemical synthesis of inorganic solids has been also shown to depend critically on the choice of mechanochemical reactor.…”

Over the decades, the application of mechanical force to influence chemical reactions has been called by various names: mechanochemistry, tribochemistry, mechanical alloying, to name but a few. The evolution of these terms has largely mirrored the understanding of the field. But what is meant by these terms, why have they evolved, and does it really matter how a process is called? Which parameters should be defined to describe unambiguously the experimental conditions such that others can reproduce the results, or to allow a meaningful comparison between processes explored under different conditions? Can the information on the process be encoded in a clear, concise, and self-explanatory way? We address these questions in this Opinion contribution, which we hope will spark timely and constructive discussion across the international mechanochemical community.

“…Appearance of Zn(H 2 O) 4 ( fum )·H 2 O as the reaction intermediate was explained by a mass action effect, as the relative amount of water to the nascent zinc fumarate polymer is large in early stages of the reaction. The described stepwise mechanism was subsequently confirmed in an independent study by the Boldyreva group [ 211 ]. A stepwise reaction sequence was also observed in the ball milling synthesis of copper(II) acetate monohydrate from CuO: milling of CuO with a stoichiometric amount of acetic acid, in the presence of a catalytic amount of H 2 O, initially yields an acetic acid solvate of the copper(II) acetate paddlewheel dimer.…”

Controlling the formation of coordination bonds is pivotal to the development of a plethora of functional metal-organic materials, ranging from coordination polymers, metal-organic frameworks (MOFs) to metallodrugs. The interest in and commercialization of such materials has created a need for more efficient, environmentally-friendly routes for making coordination bonds. Solid-state coordination chemistry is a versatile greener alternative to conventional synthesis, offering quantitative yields, enhanced stoichiometric and topological selectivity, access to a wider range of precursors, as well as to molecules and materials not readily accessible in solution or solvothermally. With a focus on mechanochemical, thermochemical and “accelerated aging” approaches to coordination polymers, including pharmaceutically-relevant materials and microporous MOFs, this review highlights the recent advances in solid-state coordination chemistry and techniques for understanding the underlying reaction mechanisms.

“…There is a phenomenon that can also be considered specific just for mechanochemical synthesis, associated with the possibility of the formation, and preservation for a sufficiently long time, of intermediate states, compounds, and even phases that cannot be formed or are unstable during thermal synthesis [196][197][198]. This phenomenon has been studied in detail in works devoted to soft mechanochemical synthesis [2].…”

Selected topics of inorganic mechanochemical synthesis are discussed. Variant mechanochemical syntheses are considered. The ex situ and in situ/operando methods to monitor the process are discussed. Methods for controlling the yield and kinetics of the mechanochemical synthesis are considered. The challenges and possible ways to address them are discussed. Thermal and mechanochemical syntheses are compared, with a special focus on mixing and milling processes. We consider the effects of various types of mechanical treatment on individual particles and on their mixtures. A special attention is paid to the macrokinetics of mechanochemical synthesis and its role in mixing and milling. The basic assumptions that render a mathematical model capable of describing the macrokinetics of mechanochemical synthesis in solid + reactive gas and solid + solid systems are written.

Abstract: We have developed a device to carry out mechanochemical reactions, which allows us to detect the intermediate products during the reaction and to stop mechanical treatment after they have been formed.
