Expressing Identity and Culture: African American Artists and Authors of Kentucky
Full text linkLibrary Fellowship for Undergraduate Students of Color, 2022 spring semesterThis project takes a deep dive into the diverse talent and accomplishments that have
existed within the African American community of Kentuckiana. The life stories and
motivations behind forty-four Black identifying artists and authors are shard. The mix of talent researched include painters, sculptors, poets, and beyond. This project was conducted in the hopes to bring light to a group of hard working people that have made great achievements in
spite of the difficult circumstances brought on by the color of their skin. For many of the authors
and artists, they used their culture and hardships as the motivation behind their work and were
able to express themselves using their selected mediums. Aside from their creative outlets, many
of these people held influential careers as educators, activists, lawyers, etc. When you take a
closer look at their work, you can see their stories come to life
Investigation on the Synthesis, Application and Structural Features of Heteroaryl 1,2-Diketones
Full text linkA set of unsymmetrical heteroaryl 1,2-diketones were synthesized by a heteroarylation/oxidation sequence with up to 65% isolated yields. Palladium catalyst XPhos Pd G4 and SeO2 were the key reagents used in this methodology, and microwave irradiation was utilized to facilitate an efficient and ecofriendly process. The application of heteroaryl 1,2-diketones is demonstrated through the synthesis of an unsymmetrical 2-phenyl-3-(pyridin-3-yl)quinoxaline (5a) from 1-phenyl-2-(pyridin-3-yl)ethane-1,2-dione (4a). The lowest energy conformations of 4a and 5a were located using Density Functional Theory (DFT) at the M06-2X/def2-TZVP level of theory. Two lowest energy conformations of 4a differ with respect to the position of the N atom in the pyridyl ring and 0.27 kcal/mol energy difference between them corresponds to 60.4 and 39.6% at 50 °C in toluene. Four lowest energy conformations for 5a have the energy differences of 0.01, 0.03 and 0.07 kcal/mol that corresponds to 26.0, 25.7, 24.9 and 23.4%, respectively. A comparison of 4a and 5a to the less hindered analogs (oxalyl chloride and oxalic acid) is used to investigate the structural features and bonding using Natural Bond Orbital (NBO) analysis
