Allylic Rearrangement In Nbs Bromination Reactions, Devann J. Harris, Bryanna L. Wichner Apr 2024

Allylic Rearrangement In Nbs Bromination Reactions, Devann J. Harris, Bryanna L. Wichner

Research & Creative Achievement Day

The allylic bromination of alkenes using N-bromosuccinimide (NBS) is a useful and selective substitution reaction, in which bromine radicals abstract hydrogen from the alkene to form a resonance-stabilized radical intermediate. However, allylic rearrangement can be a consequence of the intermediate's two resonance structures. Some literature sources imply that NBS bromination gives only one major product from asymmetrical alkenes, e.g., 2-hexene and 2-heptene, even when they should form equally stable but non-equivalent resonance contributors. In this research, bromination of trans-2-hexene was performed using cyclohexane as the solvent, and the products were analyzed using GC-MS to determine if only one product, 4-bromo-2-hexene, …

Experimental Impact Craters Into Sloped Targets, Ashley L. Miller, Mark Cintala, Christopher Cline Apr 2024

Experimental Impact Craters Into Sloped Targets, Ashley L. Miller, Mark Cintala, Christopher Cline

Research & Creative Achievement Day

Impact cratering is a process that shapes every planetary body in our solar system, including the Earth. On smaller planetary objects without atmospheres like the Moon and asteroids (e.g. Vesta and Ceres), impact cratering creates a rough surface with varying topography as opposed to a flat, horizontal surface. In general, impact cratering experiments are performed into flat targets to simplify the physics and model craters at larger planetary scales. However, the smallest craters that form on planetary surfaces are greatly affected by the local topography and cannot be understood by looking at experiments into flat targets. Dr. Anderson and her …
