The simple perrhenate salt [N(hexyl)4][(ReO4)] acts as a catalyst for the reduction of organic carbonyls and carbon dioxide by primary and secondary hydrosilanes. In the case of CO2, this results in the formation of methanol equivalents via silylformate and silylacetal intermediates. Furthermore, the addition of alkylamines to the reaction mixture favours catalytic amine N-methylation over methanol production under certain conditions. DFT analysis of the mechanism of CO2 reduction shows that the perrhenate anion activates the silylhydride forming a hypervalent silicate transition state such that the CO2 can directly cleave a Si-H bond.

About Prof. Jason Love

Jason Love obtained his PhD in rhenium polyhydride chemistry 1993 from Salford University working with John Spencer. Following a series of postdoctoral positions with Geoff Cloke (Sussex), Michael Fryzuk (UBC), and Martin Schröder (Nottingham) looking at alkene polymerisation, dinitrogen chemistry, and anion binding, he was awarded a lectureship and Royal Society URF (1999-2004) at Sussex in 1999. In 2001, he moved to Nottingham University and then to Edinburgh University as a Senior Lecturer in 2007 and Reader in 2010, where he is now the current Head of Inorganic Chemistry and Professor of Molecular Inorganic Chemistry. He has dabbled in chemistry across the Periodic Table, focussing at present on small molecule redox catalysis in relation to sustainability, and ligand design strategies for d- and f-element chemistry, supramolecular catalysis and metal extraction processes.
