Given the isolobal relationship between organoisocyanides and carbon monoxide\, these comple xes serve as mimics of the unsaturated binary metal carbonyls. The latter have traditionally been studied in either the gas phase or by matrix-isola tion techniques and\, consequently\, their condensed-phase reactivity patt erns are largely unknown. Specifically addressed will be synthetic studies that have delivered homoleptic and heteroleptic isocyanide complexes that mimic several unsaturated binary carbonyls for the middle and late transi tion metals. An emphasis is placed on the generation of anionic isocyanide complexes and their use as metal-based nucleophiles. The constrained ster ic environment enabled by m-terphenyl isocyanides has allowed for the isol ation of unique organometallic complexes when these anionic isocyanide com plexes are treated with main group electrophiles. Such systems support the stabilization of the simple 10e– diatomic molecule boron monofluoride (BF ) as a terminal ligand\, as well as diphosphorus (P2) as side-on bound lig and to a mononuclear metal center. The reactivity patterns of these comple xes are detailed\, with purpose of establishing the electronic structure f eatures of the bound diatomic ligands. Also discussed is the synthesis of other\, diatomic main-group species within the protective environment of t he m-terphenyl isocyanide framework. \n\n \n\nBio:\n\nJoshua S. Figueroa c ompleted his graduate studies at the Massachusetts Institute of Technology in 2005 under the direction of Christopher C. Cummins. From 2005-2007\, h e was a National Institutes of Health Postdoctoral Fellow at Columbia Univ ersity in the laboratory of Gerard Parkin. He started his independent care er in 2007 and is currently a Professor of Chemistry and Materials Science \, and the Leslie E. Orgel Faculty Scholar\, in the Department of Chemistr y and Biochemistry at the University of California\, San Diego (UCSD). Fig ueroa’s research and educational efforts have been recognized with a numbe r of awards\, including National Science Foundation CAREER Award (2009)\, an Alfred P. Sloan Research Fellowship (2011)\, the Presidential Early Car eer Award for Scientists and Engineers (PECASE\, 2011)\, Department of Ene rgy Early Career Research Award (2012) and the Camille Dreyfus Teacher-Sch olar Award (2012). He was named a Fellow of the Royal Society of Chemistry (UK) in 2014 and an Alexander von Humboldt Research Fellow in 2017. In 20 21\, he received a National Science Foundation Award for Special Creativit y for his synthetic work on low-valent transition metal isocyanide compoun ds. Most recently he received the 2026 American Chemical Society F. Albert Cotton Award in Synthetic Inorganic Chemistry. Figueroa’s research intere sts are focused broadly on synthetic inorganic\, organometallic and materi als chemistry\, as well as applications in catalysis. \n\n \n DTSTART:20250930T170000Z DTEND:20250930T183000Z LOCATION:OM 10\, Maass Chemistry Building\, CA\, QC\, Montreal\, H3A 0B8\, 801 rue Sherbrooke Ouest SUMMARY:Event Chemical Society Seminar: Josh Figueroa- The Carbonyl-Isocyan ide Relationship and Beyond URL:/chemistry/channels/event/event-chemical-society-s eminar-josh-figueroa-carbonyl-isocyanide-relationship-and-beyond-367858 END:VEVENT END:VCALENDAR
