Given the isolobal relationship between organoisocyanides and carbon monoxide\, these complex es serve as mimics of the unsaturated binary metal carbonyls. The latter h ave traditionally been studied in either the gas phase or by matrix-isolat ion techniques and\, consequently\, their condensed-phase reactivity patte rns 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 transit ion metals. An emphasis is placed on the generation of anionic isocyanide complexes and their use as metal-based nucleophiles. The constrained steri c environment enabled by m-terphenyl isocyanides has allowed for the isola tion of unique organometallic complexes when these anionic isocyanide comp lexes are treated with main group electrophiles. It has been recently repo rted that such systems support the stabilization of the simple 10e– diatom ic molecule boron monofluoride (BF) as a terminal ligand. The reactivity o f this complex is detailed\, with purpose of establishing the electronic s tructure features of the BF ligand. Also discussed is the synthesis of oth er\,unusual 10e– diatomic ligands within the protective environment of the m-terphenyl isocyanide framework.\n\n \n\nBio:\n\nJoshua S. Figueroa comp leted his graduate studies at the Massachusetts Institute of Technology in 2005 under the direction of Christopher C. Cummins. From 2005-2007\, he w as a National Institutes of Health Postdoctoral Fellow at Columbia Univers ity in the laboratory of Gerard Parkin. He started his independent career in 2007 and is currently a Professor of Chemistry and Materials Science\, and the Leslie E. Orgel Faculty Scholar\, in the Department of Chemistry a nd Biochemistry at the University of California\, San Diego (UCSD). Figuer oa’s research and educational efforts have been recognized with a number o f awards\, including National Science Foundation CAREER Award (2009)\, an Alfred P. Sloan Research Fellowship (2011)\, the Presidential Early Career Award for Scientists and Engineers (PECASE\, 2011)\, Department of Energy Early Career Research Award (2012) and the Camille Dreyfus Teacher-Schola r Award (2012). He was named a Fellow of the Royal Society of Chemistry (U K) in 2014 and an Alexander von Humboldt Research Fellow in 2017. Most rec ently he received a 2021 NSF Award for Special Creativity for his syntheti c work on low-valent transition metal isocyanide compounds. Figueroa’s res earch interests are focused broadly on synthetic inorganic\, organometalli c and materials chemistry\, as well as applications in catalysis.\n DTSTART:20240219T180000Z DTEND:20240219T193000Z SUMMARY:Chemical Society Seminar:Josh Figueroa-The Carbonyl-Isocyanide Rela tionship and Beyond URL:/chemistry/channels/event/chemical-society-seminar josh-figueroa-carbonyl-isocyanide-relationship-and-beyond-355235 END:VEVENT END:VCALENDAR
