Item Phenylethyloxacalixarene Synthesis Via TBS- Protected Phenylethynylcatechols(Northern Kentucky University) Montes, Luis; Saner, Stephanie; Tran, Thao; Hardy, Bailey; Kimme, BaileyThe purpose of this work is to develop a method to synthesize annulene- o,m,o,moxacalix[4]arene hybrids. These molecules are expected to adopt a conformation where the annulenes are in a close, cofacial orientation, resembling a tweezer. Once prepared, these hybrids will provide insights into the interactions between cofacial aromatic and antiaromatic systems. To develop the methodology for the synthesis of these annulene-oxacalixarene hybrids, a series p- substituted phenylethynyl- o,m,o,m-oxacalix[4]arenes is being prepared. The substituents range from strongly electron withdrawing to strongly electron donating, allowing a systematic study of the electronic nature of the phenylethynyloxacalixarenes and providing experience on how to synthesize and purify annulene compounds. This poster will discuss our progress in the preparation of the phyenyethynyloxacalixarene series.Item "Practices for a Novel Approach to Enrich Learning Experiences A pedagogical review of the novel UROCC program at NKU."(Northern Kentucky University) Trejo, Jasmine; Williams, Donald; Gatterdam, Courtney; Montes, Luis; Ma, LiliNoneItem Two Synthetic Approaches to the Formation of Oxacalixarene-Annulene Hybrid Molecules(Northern Kentucky University) Vernier, Anna; Short, Chaise; Hardy, Bailey; Saner, Stephanie; Montes, Luis; Bens, Anna; Brownstead, AdriannaThe purpose of this work is to synthesize annulene-o,m,o,m-oxacalix[4]arene hybrid molecules which exist in a tweezer-like conformation with cofacial annulenes due to the chalice-like nature of oxacalixarenes. These hybrid molecules will provide insight on interactions between cofacial aromatic and antiaromatic annulenes. To develop the methodology for the synthesis of these annulene-oxacalixarene hybrids, a series p-substituted phenylethynyl-o,m,o,m-oxacalix[4]arenes are being prepared. This poster will discuss two different approaches to the synthesis of these compounds. In the first method, the Sonogashira coupling precedes oxacalixarene formation. In the second approach, a tetraiodo oxacalixarene undergoes Sonogashira coupling with appropriate phenylacetylenes.
