Integrating Green Chemistry into Teaching Laboratories: Aqueous Suzuki-Miyaura Cross-Coupling Reaction Using a Recyclable Fluorous Precatalyst
Journal of Chemical Education, v98 n1 p203-207 Jan 2021
A method to synthesize biaryls through the Suzuki-Miyaura cross-coupling reaction using a recyclable fluorous precatalyst is described. This laboratory experiment, which demonstrates the safety benefits of green chemistry, is integrated into an upper-division course. Besides simply using the catalyst for a reaction, students can reuse the catalyst which is seldom performed in teaching laboratories. A multioutcome approach was employed for the first reaction where students are provided with different starting materials. Students elucidate the structure of the starting material/product using [superscript 1]H NMR spectroscopy. Subsequently, the precatalyst is recovered using fluorous solid-phase extraction and reused in the synthesis of a precursor to valsartan. Valsartan is a drug commonly used to treat high blood pressure. Students' feedback indicates that the laboratory session helped them better understand and apply the principles of green chemistry.
