Feisty Functional Groups: from Energetic Materials to Exotic Boron-based Molecules
Molecules bearing nitrogen oxide moieties, such as -NO2, and polynitrogen groups, such as -N3, are widely known for their potential for explosive behavior. Indeed, these functional groups lend their useful properties to most of the known energetic materials (i.e. explosives, propellants and pyrotechnics) in use today. Beyond their capricious nature, these functional groups are also powerful synthetic tools: nitrobenzene, for example, is an important precursor for the manufacture of aniline, while organic azides are used for a variety of organic transformations, including the synthesis of isocyanates (Curtius rearrangement), of 1,2,3-triazoles (Huisgen cycloaddition) and of complex nitrogen heterocycles via transient nitrenes. Two stories dealing with these very different aspects of “energetic moieties” chemistry will be presented. First, the synthesis of record-breaking monopropellants bearing both oxidizing groups (nitro, dinitramide, etc.) and “incompatible” moieties (cyanide, boron hydrides) will be described. Second, the reaction chemistry of boron species with azide derivatives, leading to a fascinating array of exotic and/or complex organoboron species, will be presented.
Guillaume Bélanger-Chabot, Ph.D., is a research felllow in the Institute of Inorganic Chemistry at the University of Würzburg in Germany, working with Professor Holger Braunschweig. Previously, he was a post-doctoral research associate at Texas A&M, working with Professor François Gabbaï. Guillaume earned his bachelor's in chemistry from the Université Laval/Université Blaise-Pascal, his master's in organometallic chemistry from the Université Laval in Québec, and his doctorate in inorganic chemistry from the University of Southern California in Los Angeles. He is a synthetic inorganic chemist with a focus on challenging synthetic targets, ranging from the synthesis of sensitive organometallic, radical or main group compounds to high-energy materials.
