Special Issue Information

Dear Colleagues,

Mechanochemistry has attracted significant interest in the last decade as a powerful, sustainable, timesaving, environmentally friendly, and more economical synthetic pathway. Mechanical activated methods are considered green and sustainable approaches to prepare a wide diversity of compounds and are currently important synthetic tools in different fields. Mechanochemistry can activate chemical transformations via mechanical forces, e.g., compression, shear, or friction, in the solid phase free of solvents or with catalytic amounts of solvents. The advantages of mechanochemistry go far beyond the non-use of solvents, as it is a highly efficient technique, involving low costs, as well as reduced energy usage and CO2 emissions.

The main aim of this Special Issue on “Mechanochemistry: New Perspectives of Green Chemistry” is to create an open forum where scientists can share their research and discoveries in this promising field and increase their visibility along with interaction with industries and production systems. The contributions to this issue, in the form of original research or review articles, may cover all aspects of mechanochemistry.

Abstract
A new mechanically stimulated solid-state reaction of PtCl4 with sodium β-diketonates has been discovered. Platinum (II) β-diketonates were obtained by grinding excess sodium trifluoroacetylacetonate Na(tfac) or hexafluoroacetylacetonate Na(hfac) in a vibration ball mill, followed by subsequent heating of the resulting mixture.

A new mechanically stimulated solid-state reaction of PtCl4 with sodium β-diketonates has been discovered. Platinum (II) β-diketonates were obtained by grinding excess sodium trifluoroacetylacetonate Na(tfac) or hexafluoroacetylacetonate Na(hfac) in a vibration ball mill, followed by subsequent heating of the resulting mixture. The reactions occur under much milder conditions (at about 170 °C) compared to similar reactions of PtCl2 or K2PtCl6 (at about 240 °C). Excess diketonate salt plays the role of a reducing agent in the conversion of Pt (IV) salt to Pt (II) compounds. The effect of grinding on properties of the ground mixtures was studied by XRD, IR, and thermal analysis methods. The difference in the course of the interaction of PtCl4 with Na(hfac) or Na(tfac) indicates the dependence of the reaction on the ligand properties. The probable reaction mechanisms were discussed. This method of synthesis of platinum (II) β-diketonates makes it possible to substantially reduce the variety of reagents used, the number of reaction steps, the reaction time, the use of solvents, and waste generation compared to conventional solution-based methods.
