ABSTRACT:  The catalytic functionalization of unreactive small molecules such as methane via C-H activation is a long-standing goal in organometallic chemistry. Late transition metals, such as platinum, have been shown to be quite effective in breaking strong C-H bonds. Recently, we have been exploring the feasibility of catalytic methane functionalization employing aryl halides as oxidants. Key challenges include the unreactive nature of Pt(II) toward intermolecular aryl halide oxidative addition, and the challenges with balancing the preference for Pt(II) versus Pt(IV) oxidation states. We have recently discovered Pt(II) complexes that are capable of intermolecular oxidative addition of aryl halides under ambient conditions.  We have also designed and developed new hemilabile P,N ligands that facilitate both oxidative addition and reductive elimination relative to more conventional N,N or P,P ligands. Notably, only the P,N ligands with significant steric bulk at phosphorus were capable of forming the strained chelates. These results will be discussed in the context of our ongoing efforts to catalytically functionalise methane.

BIO:  Prof. Jennifer Love began at UBC as an assistant professor in 2003, following her doctoral studies with Prof. Paul Wender at Stanford University and NIH-funded postdoctoral studies with Prof. Robert Grubbs at Caltech. She has won a number of awards, including the IntelliSyn Pharma Award from the Canadian Society for Chemistry in 2018, an Alexander von Humboldt Research Fellowship for Experienced Researchers in 2012, the AstraZeneca Canada Award in Chemistry in 2008, the UBC Science Killam Teaching Award in 2009 and a CNC IUPAC travel award in 2011. She became a Fellow of the Royal Society of Chemistry (UK) in 2016. Her program is well-funded and internationally recognized. She has given over 100 invited presentations around the world. She has served as the vice-Chair, Chair and past-Chair of the Inorganic Division of the CSC. She is an Associate Editor for Catalysis Science & Technology and has served on both the editorial board and editorial advisory board of Dalton Transactions. She recently began as a Responsible Editor for Organic Reactions. Love’s program spans the traditional boundaries of organic and inorganic chemistry. Her group aims to develop fundamentally new, cost-effective and low-waste reactions for the synthesis of medicinally important compounds by exploring the mechanism of reactions at late transition metal centres.

Dr. Love is the guest of Dr. Marek Majewski.
