New Hexaorgano guanidinium or-gano carbonates and related salts for use in batteries, chemical syntheses (e.g., SILP), biological applications

The invention provides novel hexaorgano guanidinium or-ganocarbonates that can be used to produce other hexaorgano guanidinium salts through anion metathesis. The metathesis reaction according to the invention is highly efficient, as it enables quantitative production of the hexaorgano guanidinium salts. The method also avoids toxic byproducts. Both the hexaorgano guanidinium organocarbonates and hexaorgano guanidinium salts obtainable therefrom are halide-free ionic liquids and are thermally stable. They have many potential applications, for example in chemical syntheses, adsorption heat pumps, and elec-trolyte systems (e.g., batteries, photovoltaics).
