“…See DOI: 10.1039/ c9gc00783k a 4-Methyl-5-imidazolecarboxaldehyde and zinc acetate, the linker and metal source for ZIF-94, are currently commercially available. Importantly 4-methyl-5-imidazolecarboxaldehyde is a good candidate for production using mechanochemical routes, 22 suggesting this can be produced with minimal environmental impact and zinc acetate, being a salt, can be precipitated from aqueous conditionsfurther reducing the use of organic solvents.…”

“…Even though CuAAC reactions are proficiently performed in conventional solution phase, there is an increasing demand for non‐conventional approaches such as mechanochemistry (ball milling), microwave and ultrasound irradiation in terms of economical (feedstock) and environmental (energy consumption) response . Particularly ball milling, is known as mechanical force‐induced chemical transformations, has been rapidly progressing in various fields such as organic synthesis, inorganic and supramolecular materials . It is pertinent to note that this method has been successfully implemented in copper‐catalyzed azide‐alkyne cycloaddition for the synthesis of 1,2,3‐triazoles …”

Herein, we designed and synthesizeda series of 1,2,3‐triazole tethered 3‐hydroxy‐2‐oxindoles (4 a‐j) using N‐propargyl isatin derivatives as key starting materials (1 a‐d) under ball‐milling conditions by merging aldol condensation and click reaction. The synthesized compounds (4 a‐j) were examined for their corrosion inhibition behavior in mild steel using gravimetric and electrochemical analysis. The compound 4 i was identified as the most efficient compound with an efficiency of >70%. Also, the adsorption of inhibitors on the surface of mild steel and mixed type of behaviors was evidenced by impedance and Tafel polarization studies, respectively. Further, the evaluation of antibacterial and antifungal activities demonstrated that compound 4 gpossessed a significant potential to behave as an antimicrobial agent.

“…The use of external stimuli to induce solid state reactivity can be studied by different approaches such as light induced reactivity [9][10][11][12][13], mechanical reactivity [14][15][16], high pressure reactivity [17,18], thermally induced reactions [19][20][21][22], or a combination of temperature and other aspects that might influence the reaction [23]. High temperature synthesis in MOMs is very appealing as often many synthesized materials obtained as kinetic products can be transformed into more stable thermodynamic structures upon heating.…”

Thermal treatment is important in the solid-state chemistry of metal organic materials (MOMs) because it can create unexpected new structures with unique properties and applications that otherwise in the solution state are very difficult or impossible to achieve. Additionally, high-temperature solid-state reactivity provide insights to better understand chemical processes taking place in the solid-state. This review article describes relevant thermally induced solid-state reactions in metal organic materials, which include metal organic frameworks (MOFs)/coordination polymers (CPs), and second coordination sphere adducts (SSCs). High temperature solid-state reactivity can occur in a single-crystal-to-single crystal manner (SCSC) usually for cases where there is small atomic motion, allowing full structural characterization by single crystal X-ray diffraction (SC-XRD) analysis. However, for the cases in which the structural transformations are severe, often the crystallinity of the metal-organic material is damaged, and this happens in a crystal-to-polycrystalline manner. For such cases, in the absence of suitable single crystals, structural characterization has to be carried out using ab initio powder X-ray diffraction analysis or pair distribution function (PDF) analysis when the product is amorphous. In this article, relevant thermally induced SCSC reactions and crystal-to-polycrystalline reactions in MOMs that involve significant structural transformations as a result of the molecular/atomic motion are described. Thermal reactivity focusing on cleavage and formation of coordination and covalent bonds, crystalline-to-amorphous-to-crystalline transformations, host–guest behavior and dehydrochlorination reactions in MOFs and SSCs will be discussed.
