Abstract: We have previously exploited Frustrated Lewis pair (FLP) chemistry for the activation of H2, hydrogenation catalysis and the capture of small molecules. More recently we have uncovered evidence of both heterolytic and homolytic reactions for select FLPs affording either ionic or radical reaction pathways. The access to radical pathways has been extended to develop novel air stable main group derived radicals as well as one-electron FLP chemistry. Other efforts in expanding this concept, have focused new intramolecular FLPs, the activation of N2-surrogates, main group cations, ionic systems and two coordinate borinium cations. The further potential of these and related main group reagents in synthetic and catalytic synthetic chemistry is considered.

About the speaker: Prof. Doug Stephan, born in Hamilton, graduated with his BSc at McMaster (1976) and completed his PhD at UWO (1980). He then held a NATO PDF at Harvard, before beginning his independent career at the University of Windsor (1982). He was promoted to Associate Professor (1985), full Professor (1992) and named a NSERC Industrial Research Chair (2001), University Professor (2002) and Canada Research Chair(2005). In 2008 he moved to the University of Toronto as a Professor and Canada Research Chair, In 2018, he was appointed University Professor (top 1% of faculty at U of T). He was an Associated Editor for Chem. Soc. Rev. for 6 years and served as the Chair of the editorial board for 4 years. While a highly successful world-leading researcher in inorganic chemistry/catalysis prior to his move to University of Toronto, the impact of his work exploded since the move. In articulating the concept of “frustrated Lewis pairs (FLP)” in 2006 Stephan established himself as the founder of the field of FLP chemistry. The impact of Stephan’s work is clear, with over 500 publications drawing more than 27000 citations and an H-index of 80. Stephan has received recognition for his work including the 2001 Alcan Award (Canadian Society for Chemistry). an Av Humboldt Foundation Senior Research Award (2002), NSERC Synergy Award (2003), Ciapetta Lectureship Award (2004, North American Catalysis Soc.) and the LeSueur Memorial Award (2005, Canadian Soc. Chemical Industry). He was appointed as a Fellow of the Royal Society of Canada in 2005, awarded a Killam Research Fellowship (2009-2011), a Senior Award re-invitation from the Humboldt Foundation(2011), the Ludwig Mond Award and Lectureship (Royal Soc. Chemistry UK, 2012) and the 2013 H.M. Tory Medal from the Royal Society of Canada. He was elected a Fellow of the Royal Society (2013, London). In 2014, he was elected a Corresponding Member of North-Rhein-Westfaelia Academy of the Sciences and Arts (Germany) and awarded the Applied Catalysis Award (Royal Society of Chemistry, UK), Canadian Green Chemistry and Engineering Award and Chemical Institute of Canada Medal. In 2015, he was a Distinguished Adjunct Professor, King Abdulaziz University and in 2016-2019 was named an Einstein Visiting Fellow at the Technical University of Berlin. For each of the last 6 years, he has been named to the Thomson Reuters Highly Cited List, and in 2015 named to the List of World’s Most Influential Scientific Minds. In 2019 he was awarded the NSERC of Canada John C. Polanyi award as well as the E.W.R Steacie award from the Canadian Society for Chemistry.
