Organolithium reagents are synthetically useful because they are strong bases, great nucleophiles, and effective catalysts for radical and anionic polymerizations. Such reagents are, however, very reactive, often spontaneously catching fire in air. To control these hazards, they are only commercially available as solutions in hydrocarbons or ethers, which cause challenges. Little can be done to modify the reactivity or selectivity of ordinary organolithium reagents, yet modification is a growing need in many chemical industries.
SiGNa Chemistry has transformed organolithium reagents into dry, free-flowing, stabilized powders in nano-structured alumina. These resulting powders perform all the reaction types of conventional organolithium compounds, such as nucleophilic additions, initiation of polymerizations, and base-catalyzed reactions, among others. The powders are infinitely stable under nitrogen gas at room temperature and extend the chemical toolbox of commercially available organolithium compounds.
Currently SiGNa is working on the next element in the alkali metal family, Lithium. A number of new discoveries have been made. Read More
