Abstract
We have developed a ring-opening metathesis polymerization (ROMP) experiment for our inorganic laboratory that makes use of a 7-oxanorbornene monomer prepared by the students in our introductory organic course. The catalyst utilized is a commercially available, well-defined ruthenium carbene complex that promotes the living polymerization of norbornene derivatives. The metathesis polymer can be characterized by NMR spectroscopy to determine the distribution of cis and trans double bonds. To accompany the preparative polymerization, we have also developed an NMR study that allows the students to observe the active catalytic species during the course of the reaction and to qualitatively monitor the progress of the reaction. This experiment provides students with the opportunity to gain firsthand experience performing reactions in an area of polymer chemistry that is at the forefront of modern research.
