Mechanochemical syntheses of Ru(II) complexes with isothiazole-type of ligand

Abstract

Mechanochemistry is concerned with chemical transformations induced by mechanical means such as pressure, shear or friction. The main advantage of mechanochemistry is its focus on green chemistry, which is based on the pharmaceutical and chemical industry's need for cleaner, safer and more efficient transformations. The hallmark of mechanochemistry is the performance of chemical transformations by grinding or milling, without the need for large amounts of environmentally harmful solvents. In this paper, the mechanochemical synthesis and characterization of the [Ru-(ɳ6-p-cymene)Cl2L] complex with the ligand 5-(methylamino)-3-morpholine-4-ylisothiazole-4‐carbonitrile are presented. The complex was obtained in good yield as an orange-coloured powder and was characterized by FTIR. Mechanochemistry is a broad field that is applicable to subjects from triboemission to the direct manipulation of individual molecules, mechanical alloying, and organic synthesis. It has a fascinating history and promises interesting new results and a variety of applications in the future.
