From sulfonium salts to samarium catalysis: new radical chemistry for synthesis
Presented by Minakem
Mar 22, 2023 — All day
The Department of Chemistry and Biomolecular Sciences hosts guest speakers from the industry, research institutes, other universities, and from our own campus as part of a regular seminar series during the Fall and Winter terms.
Abstract
Part I – Our approach to the development of transition metal-free cross-coupling processes is based on the proposal that sulfur can replace metals in activating substrates and generating reactive intermediates for exploitation in C–C bond-formation. In particular, we will describe the exploitation of in situ generated aryl sulfonium salts in photocatalytic and photochemical coupling processes involving aryl radicals.
Part II – Samarium(II) iodide is one of the most widely-used single electron transfer (SET) reductants in chemistry. We will showcase the reagent’s ability to unlock key steps in natural product synthesisand will describe our recent studies on catalysis with SmI2.
